NATURAL RESOURCES DEPARTMENT LAND MANAGEMENT AND WILDLIFE RESEARCH SUMMARY FOR 2012 Prepared February 2013 By Drew Ullberg Forest Preserve District - Kane County 1996 S. Kirk Rd Geneva, IL 60134 Introduction and Background The Forest Preserve District of Kane County (District) was organized in 1925 with the defined purpose of acquiring, preserving and managing land for public use and enjoyment. Land acquisition had a humble beginning, when 97.5 acres were purchased in 1926 to create the Johnson’s Mound Forest Preserve. From this first purchase through the first 65 years of existence, the District sought to establish a preserve in each township so all county residents had equal opportunity to enjoy public open space. Although originally purchasing land for open space preservation, by default the District became the local entity saving vestiges of the historic Illinois landscape. By 2012, District holdings had grown to 20,000 acres and staff were hard at work managing natural areas concurrent with documenting the diversity of flora and fauna that depend upon it’s holdings. The role of managing and maintain the biodiversity and function of this land is the responsibility of the District’s Natural Resources Department. Formally organized in 2005, the Natural Resources Department (Department) is composed of 7 full-time staff, including: • 1 – Director (Drew Ullberg) • 1- Restoration Ecologist (Ben Haberthur) • 1- Wildlife Ecologist (Bill Graser) • 1- Senior Restoration Technician (Jason Johnson) • 3 - Restoration Technicians (Pete Dall, Andy Olnas and Pat Chess) The mission of the Department is to ensure the preservation of native flora and fauna diversity through the protection, maintenance, restoration or reconstruction of native ecosystem types. Specific Department goals and objectives were presented in the District’s 2008 Master Plan and are provided here as Appendix 1. Each year a wide variety of natural areas management projects are planned and then implemented by Department staff, with the assistance of contractors and citizen volunteers. This report provides a look back at 2012 in terms of what types of projects were completed and what amount of staff time was dedicated to specific activities. Beginning in 2008, a data system was setup to track field staff time devoted to land management work. Data is presently recorded for major types of work, location, number of staff involved per task and hours devoted per task. Tracking of staff time has proven valuable and has allowed more rapid preparation of monthly reports present to the Board of Commissioners. This report has been formatted so that information on each major activity is summarized in one or two pages. It is important to note that the Operations and Maintenance Department as well as Volunteers assist the Natural Resource Department in a variety of areas. That assistance is noted throughout the report within specific areas of management. -1- 2012 Accomplishments This report provides descriptions for major task categories and related number of hours tallied are presented in graphs. A separate category for Wildlife management & studies is presented near the end of this document. Where possible, photos of notable projects are included. Work is reported here on these 9 activity categories: 1. Prescribed Burning 2. Plant propagation 3. Research / Monitoring 4. Seed Harvest & Cleaning 5. Seed Planting 6. Tree / Brush Clearing 7. Tree Planting & Tree Care 8. Weed Management-herbiciding 9. Weed Management-mow, etc Completion of any natural areas management project is highly dependant upon season of the year and weather during that season. Below is a table showing the type of activities staff tackle during the year: LAND MANAGEMENT ACTIVITIES – ROUGH TIMETABLE ACTIVITY J F M A M J J A S O N D Cut & herbicide tree stumps Tree & shrub thinning Prescribed burns- Woodland Tree planting Install native prairie seed mixes Herbicide garlic mustard rosettes Herbicide reed canary grass Prescribed burns- Grassland Pull garlic mustard Herbicide thistle Install plugs/potted plants Mow field thistle Mow giant ragweed Mow sweet clover Herbicide invasive trees – basal bark Herbicide purple loosestrife Seed harvesting -1- Below is a table which contains all the major activity groups that were tracked during the year. Only those items highlighted in yellow are discussed in greater detail. It is interesting to note that the hours for office tasks (planning, report preparation, research) exceeded hours in 2012 logged for tree and brush clearing.

Time dedicated to grant writing, administrative tasks, Director’s field time, and related staff training or/mentoring is not included. For all of 2012, a total of 11,652 working hours were tracked for all levels of activity. When we subtract from 11,652 those hours for staff time off (holiday/vacation/sick leave), driving time, work completed at the Aurora West – Natural Resources Facility on muddy/rainy days, office tasks, meeting and planning time, then on-theground natural areas management was 5,023 hours. One of the largest non-land management activities for 2012 was driving, where 1,428 total hours were logged. -2- Activities per Season To give the reader a sense of which tasks are undertaken during our four seasons, an Activity per Season chart and table have been prepared. Many tasks overlap from one season to another, such as seed harvesting or tree & brush control; however some work is more restricted to one season, such as weed control with herbicides. For the purpose of this report seasons of the year are defined as: • Spring = March, April, May, • Summer = June, July, August, • Fall = September, October, November, • Winter = December, January, February, During the spring months, the top activity by logged hours was plant propagation (416 hours) followed by weed herbiciding (239 hours). In the summer of 2012, weed herbiciding (532 hours) was the major activity, followed by plant propagation (330 hours). By contrast, in the fall more hours were logged for tree and brush clearing (317) than for the next two leading activities (tree planting or plant propagation or prescribed burning) combined. Tree and brush thinning, and the associated stump herbiciding work, was the major winter activity recorded at 604 hours.

All our native ecosystems need fire to thrive. The most effective way to reinvigorate our lands is to reintroduce that primal natural force that shaped the diversity of the prairie biome eons ago. The use of fire to manage natural communities dates back centuries. Presently, however, fire is the most cost and time effective means to control brush, setback weedy species, recycle nutrients and burning reduces thatch thereby easing seed installation. A total of 947 hours were devoted to the District’s Prescribed Burn efforts in 2012. Both the Natural Resources and the operations and Maintenance Departments dedicate a considerable amount of time to the District’s prescribed burn program. Natural Resources is the lead department developing/overseeing the overall burn program. In 2012, Natural Resources attributed 386 hours to the program, which includes administration, and site work, while Operations and Maintenance staff contributed 561 hours with on-site burn assistance. The Natural Resource Department figure includes time spent conducting burns, preparation of burn maps and plans, cutting burn breaks, preparing burn equipment and field checking sites for burn readiness. Twenty-two individual burns were completed across 13 different preserves. The two largest burns were at Aurora West (190 acres) and at Burnidge (229 acres). Operations Department staff separately contributed 561 staff hours to conducting prescribed fires.

These plants were used to start a seed nursery at the Aurora West -- Natural Resources facility. The goal of creating a seed nursery was to establish a reliable, annual seed source for hard to find native plants. Since 2007, staff has grown numerous flats of prairie flowers and grasses from nursery seed for later outplanting. Some of the nursery seed is used to grow plants for the Prairie @ Home program, where Kane County homeowners are given native plants, with the agreement they maintain the plants then harvest & return the seed to the District. As of 2012 there were 31 different plant species in the seed garden, including the federally threatened leafy prairie clover (Dalea foliosa). Pot grown trees and shrubs are also produced in-house from locally harvested seeds and nuts. In 2012 staff grew white oak, bur oak, red oak, chinquapin oak, Kentucky coffee tree, Kingnut hickory, shagbark hickory, blue ash, wild plum, alternate-leaved dogwood, american hazel, button bush, wafer ash, speckled alder (a State endangered species), bog birchshrubby St. John’s wort. Many of these trees and shrubs will be used in future reforestation projects. An inventory of on-hand pot grown trees & shrubs is found in Appendix 2 For all of 2012 staff devoted 936 hours to managing the seed garden plus growing and caring for thousands of pot grown trees and shrubs. 2012 Natural Resource Staff Plant Propagation & Care 448 500 400 300 200 249 167 73 100 0 Maintenance Planting Propagation Weeding -6- Research and Monitoring – 258 hours Department staff engages in a variety of annual and unique scientific research that is separate from work conducted by Bill Graser, our Wildlide Biologist. Of the more than 94 properties owned by the District, baseline tree surveys, woodland characterization or timber cruise data are lacking for 33 sites. Likewise, we lack good data on the spring woodland flora for dozens of woodlands. Each year we prioritize to evaluate trees Wild chervil study and spring flora with work usually completed at 4 or 5 sites annually. Of the 258 hours dedicated to research and monitoring this past year, 49 hours was spent on tree surveys and 26 hours used for spring vegetation surveys. Other notable projects from 2012 were an experiment measuring the efficiency of different herbicide treatment for Wild chervil control, a study of prairie vegetation height and density using the Robel Pole method, and many regionally rare plants were monitored as part of the six county Plants of Concern (POC) project.

Without native seed we could not restore or improve our native ecosystems. Indeed, the fuel that powers the restoration engine is seed. Without an annual and reliable source of locally grown seed, work on new prairie recreations would come to a halt. Likewise, we would drastically reduce the acreage of woodland brush clearing if seed needed to re-vegetate and stabilize our woodlands was not available. Seed harvests were accomplished in two modes during 2012: 1) hand harvests by staff and 2) hand harvesting by volunteers. The Department logged 109 hours supervising and assisting on volunteer harvests, while staff directly spent 124 hours collecting seed. The drought of 2012 decreased the amount of wild seed produced and the amount of time harvesting was close to one-half the hours spent collecting in 2011. In the last year seed of 49 species were collected, totaling 205 pounds when cleaned and commercially valued at roughly $72,160 [= (205 x16oz) x $22/oz.]. As in past years, staff has expended a lot of energy --totaling 413 hours -- in 2012 to dry, sort, mill, process, and clean wild harvested seed all leading up to creation of native seed mixes. A dedicated corps of volunteers contributed 333 hours to seed collecting in 2012.

Months after a woodland is cleared of brush, staff will return to manage stump re-sprouts and control garlic mustard. Ground cleared of brush also should be seeded with native species to prevent a massive weed invasion. When working to create a prairie from cropland, seed is usually installed in the late winter after the final soybean crop is harvested. Mowing weeds is once monthly following the initial seeding. Prairie recreations which are several years old are also over-seeded after a burn to fill in weedy spots or to boost overall plant diversity. Due to the 2012 drought, staff spent only 95 hours sowing seed. For comparison, staff dedicated 281 hours to installing seed in 2011. Sixty-seven acres of farmland were removed from production to accommodate seeding in 2012. Also, at Johnson’s Mound, twenty acres were removed from crop production so cover crop grass could be established in advance of a planned 2014 reforestation effort. Woodland seed mixes were installed at Bliss Woods and Lone Grove.

The six major categories under tree and brush clearing tracked last year were 1) tractor mowing brush, 2) leading volunteer brush cutting workdays, 3) cleanup of slash following a chainsaw or volunteer brush cut, 4) staff chainsaw tree felling projects, 5) felling trees with the ASV tree shear, and 6) ASV brush mowing using the FECON forestry mower. The top four chainsaw tree felling projects by tallied hours were at 1) Fabyan - to thin brush near the dolomite prairie on the west bank of the Fox River (144 hours) 2) Campton - to clear wind snapped trees plus dead black locust trees near the entrance (97 hours) 3) Aurora West -to fell hundreds of EAB killed ash in an old nursery planting along Hankes Road (61 hours) 4) Fitchie Creek - to remove both an island of trees among an oak planting and remove hundreds of dead box elder near the parking lot off Russell Road (62 hours). The top two brush mowing sites in 2012 were also at Fabyan and Aurora West - Culver, with 46.75 and 33 hours respectively. In addition to the staff hours, our volunteers contributed an astounding 3,062 hours to tree and brush cutting in 2012. 2012 Natural Resource Staff Tree & Brush Clearing ASV Brush Mowing 195 12 Recon 5 Chainsaw Projects 479 Site Clean-up 202 Tractor Mowing 144 Volunteer Brush Cuts 107 0 50 100 150 200 250 300 HOURS 350 400 450 500 Natural Resource Staff: 2012 Brush Mowing Per Preserve Hours Aurora West 46.75 50 Campton 45 Culver 40 33 35 Hours ACTIVITY ASV Tree Shear Dick Young 28 30 25 Freeman Kame 0 Glenwood Park 12 15 5 Fitchie Creek 19.5 20 10 Fabyan 25.5 7 3 8.5 4.5 Preserve Kenyon Farm 5.5 2 LeRoy Oakes Miscellaneous Lands Rutland - 10 - Natural Resource Staff: 2012 Chainsaw Project Hours 144 97 62 44 11 53 9 61 150 125 100 75 Hours 50 25 0 Preserve - 11 - Weed Management- herbiciding – 975 hours Weed management has always been a challenge for the District. As land is added to the District system, or Canada thistle invades new areas, or land is converted from row-crops to tallgrass prairie, the need to conduct basic weed management increases. A wide variety of weeds grow across our lands, but in terms of management, priority is given to controlling those species listed as noxious or exotic per the Illinois Noxious Weed Act and the Illinois Exotic Weed Act. Examples of target species include Canada thistle (Cirsium arvense); giant ragweed (Ambrosia trifida), and purple loosestrife (Lythrum salicaria). During all of 2012, Natural Resource staff spent 975 hours on all forms of weed herbiciding. Presented in the chart below is the breakdown of hours by 1) boom spray, 2) hand spray, 3) weed scouting, and 4) stump treatment. Extremely hot weather in 2012 prevented staff from completing many herbiciding projects. Herbicide Management in 2012 638 375 257 Hours 300 225 150 75 48 33 0 Most Canada thistle populations on District lands are mowed. Since 2000, extremely large and/or hard to mow clusters of this plant have been herbicided using a tractor towed boom sprayer. In 2010-11, 40 hours were invested in boom spraying Canada thistle. Hot weather in 2012 prevented boom spraying. Weed Management by Herbicide Form Canada thistle - 12 - Weed Management- herbiciding (continued) A core group of 20 plant species are treated with herbicide each year. Below is a chart depicting the top 10 plants targeted throughout 2012. While most weed herbiciding occurs between May and September, during fall and winter tree felling operation, stumps are herbicided to prevent stump resprouting. The top three weed receiving herbicide treatments in 2012 were teasel, wild chervil and purple loosestrife. Purple loosestrife continues to invade many high quality wetlands and is so aggressive it can quickly outcompete native plants. Boom spraying this plant is also not an option, thus careful hand spraying herbicide is necessary to avoid killing desirable plants. Additionally, both teasel (two forms) and Wild chervil are more frequently invading our preserves, mainly from established, unmanaged old field and roadside right-of-way populations. Top 10 Plants: Herbicide Management in 2012 Hours 150 145 139 131 100 60 50 53 49 46 45 44 42 41 0 Plant Name Purple loosestrife (above) is an aggressive invader of our wetlands. Controlling this plant takes repeated herbicide treatments over several years. Over 400 hours were devoted to cut stump and stump resprout treatment during the last year. This is a good representation of the level of follow-up effort required after a tree felling project is complete- meaning there is more to the project than cutting down trees and removing the slash. Left untreated, winter cut trees and brush re-sprout with vengeance during the following spring. Control of box elder, buckthorn and honeysuckle resprout using herbicide occurred primarily at Burnidge, Fabyan, Dick Young, and Johnson’s Mound in 2012. - 13 - Weed Management - mowing , cutting & pulling – 265 hours The second type of weed management undertaken by staff entails the physical cutting and/or removal of herbaceous plants through mowing, cutting or pulling. For all of 2012, a total of 265 hours were tallied across these activity categories: 1) Hand cutting, 2) mowing, 3) mowing recon (scouting for weeds to mow), 4) garlic mustard pulling by staff and 5) staff led volunteer weed control days. Weed Mowing and Cutting in 2012 5 6 38 33 Hours Spent 184 Hand Cutting Mowing Mowing Recon Pulling Volunteer Days In 2012, 184 hours were logged for wildland weed mowing, mainly accomplished with our 15 foot wide Schulte mowers powered by either the John Deere 6410 or 6420 tractors. The primary targets were fields of white –sweet clover (Campton, Meissner-Corron and Dick Young preserves) and patches of Bradford pear (Dick Young and Schweitzer Woods preserves) Top Species Mowed or Hand-Cut in 2012 140 120 Hours 100 139 80 38 60 40 20 1 15 2 18 15 0 Plant Name White-Sweet Clover (Top) (Lower) Garlic mustard - 14 - Tree / Shrub Planting - 582 hours Starting in 2007, the Department made a dramatic shift in long- held reforestation practices and began planting 3 foot tall bare root saplings and pot grown trees instead of small bare root whips. A large mass of fine roots gives pot grown trees a much better chance of survival compared to small bare root stock trees. Pot grown trees are planted both spring and fall. Staff, with extensive help from volunteers, planted a total of 912 pot grown oak trees in 2012. Most of those trees were grown in 5 gallon pots and measured 2 feet tall. A mix of red, black, white, and bur oak were planted this year. Specifically, 412 oaks were planted at Aurora West during National Public Lands Day, 400 oaks were planted at Schweitzer Woods during Earth Day 2012, plus 100 oaks were planted at Dick Young as part of a Veteran’s Conservation Corps event. Volunteers contributed a combined total of 887 hours during the National Public Lands Day and Earth Day events. Tree Planting Hours for 2012 487 500 Hours 400 300 200 35 100 61 0 Maintenance / Prep Planting Volunteer Events Activity Hundreds of plants and trees awaiting installation Staff – aided by volunteers – planting trees Our new standard for reforestation includes watering each tree as it is planted, followed by mulching, then a four foot long 2” x 2” stick is installed by each tree. This stick is then sprayed with a non-toxic deer repellant several times until winter. - 15 - The single largest category of work related to reforestation involved the follow-up watering and deer repellant applications. Due to the drought of 2012, staff spent a large amount of time (over 400 hours) hauling then watering newly planted trees to keep them alive. Tree Care stewards – specialized volunteers – logged 70.5 hours involved in deer repellant application in 2012. Hundreds of trees were rapidly planted by eager volunteers during National Public Lands Day Jason Johnson applies deer repellant to a wood stake next to a freshly planted oak - 16 - Wildlife Studies – 1,869 hours Bill Graser joined the Natural Resources Department in late 2008. Right at the beginning of his career here, Bill made plans for documenting amphibian and reptile populations, plus planned to study the white-tailed deer populations at numerous preserves. Most of the hours Bill logged in 2012 were tied to tasks related to white-tailed deer projects (690 hours). Dozens of hours were spent obtaining then reviewing current wildlife literature, writing documents as foundation for the Deer Management Program, writing the Deer Management Strategy & Plan document, preparing deer related presentations for District committees, and most importantly implementing all aspects of the new archery hunting program. Though less than two dozen deer were harvested from District lands between November 2012 and midJanuary 2013, the program got off to a positive start. Each and every one of the 33 deer hunters were pleased with the Commission approving of this recreational activity, and everyone involved understanding the ecological importance of reducing the deer herd. In 2012, archery hunting was only allowed at the northern segment of Freeman Kame – Meagher and across the Brunner Family Forest preserves. There was not enough of a consistent snow cover between January and February 2012 to allow Department staff to conduct our annual deer population counts from a helicopter. Wildlife Biologist’s Time - 17 - Bill Graser inspects a check in box for records of hunting activity One of our lucky archery hunters with his prize Although the establishment of a wildlife biologist position in 1994 has allowed the District to implement a considerable number of wildlife surveys, we still lack data on frog, snake, turtle and salamander populations (collectively called “herpts” or “herptiles”) for dozens of preserves. In 2012, Bill conducted snake surveys at a Aurora West, Campton and part of the Dick Young Forest Preserves. No highly conservative snakes were recorded. Briefly, our snake sampling method entails distributing 2’ x 3’ plywood boards across a field in early spring. The GPS location of each board is mapped, then revisited and lifted several times during the summer months. Snake survey work - we got some big ones! Another component of the annual herpt surveys involves netting and monitoring turtles. Since 2008 we have emphasized trapping for, then radio tagging and tracking Blanding’s turtle – an Illinois State Endangered species. Usually Bill and his intern are knee to waist deep in water from June to August at least twice a week netting or tracking this species. Not so in 2012, due to the drought, there was more mud than water. Actual radio tracking of turtles ended a month early last year due to the drought. - 18 - Photos from top left to right: A Blanding’s turtle; netting for turtles; and bottom – a freshly mounted radio transmitter on a Blanding’s turtle. A very limited small mammal census was conducted by staff at three sites in 2012 (Aurora West, Blackberry Maples and Campton). No rare or endangered species were found, just the usual voles, mice and shrews. - 19 - APPENDIX 1 Forest Preserve District of Kane County Natural Resources Department GOALS AND OBJECTIVES 1) Maintain biological diversity in all designated Illinois State Nature Preserves. • • 2) Evaluate ecological health of all District lands. • • • • • • • • 3) Conduct multi-tiered herbaceous vegetation analysis across plant communities to document baseline pre-restoration/enhancement conditions. This effort shall document species presence and abundance. Collect data on woodland composition, quality, structure and age classes across all holdings. Expand in-place butterfly, amphibian and avi-fauna monitoring programs which involve both volunteers and staff. Hire full time Wildlife Biologist to implement mammal monitoring programs. Initiate limited scope small mammal census projects at high quality sites and establish restoration units. Further support volunteer based aquatic/stream ecosystem monitoring and avi-fauna monitoring programs. Support and expand involvement in the regional rare plant monitoring project titled Plants of Concern. Conduct field evaluations of dominant habitats at critical preserves, such as Johnson Mound, Burnidge, Helm Woods, and Freeman Kane and determine plant community quality. Quality may be based on the Illinois Natural Area Inventory system. Develop plans which identify site specific land management needs. • • • • 4) Implement and evaluate prescribed burn regime across all nature preserves. Reduce and/or eliminate all non-native and invasive plants and animal species which immediately threaten plant community integrity. Establish management objectives for all primary habitat types on District lands. Prepare Annual Management Schedule booklet which outlines proposed restoration projects and objectives for site receiving management efforts. Refine existing ARC Map/GIS data files and layers to reflect and incorporate present and projected plant community quality. Draft management unit maps for all lands purchased between 1980 – 2005 and not currently undergoing large-scale land restoration. Maintain and enhance the overall biodiversity, quality and character of 90% of District lands preserved as natural habitat and open space. • Continue to implement common land management techniques such as plant control, prescribed burning, and wildlife control, seeding and planting. - 20 - • • • • • • • • • • 5) Conduct routine evaluations of land management methods and techniques to measure effectiveness. Adjust tactics to improve results and achieve land management goals, e.g. adaptive management. Continue to hire qualified contractors to assist with large-scale restoration and enhancements projects (e.g. tree thinning, herbicide application, etc.) Increase species diversity and restore community structure upon lands degraded by past land uses and/or invasive species. Annually remove 200 – 300 acres of land from the farm lease program. This land shall then be planted to improve habitat valve to wildlife. Annually plant 5,000 – 10,000 oak seedlings across the appropriate habitats. Focus management activities on these lands where; 1.) Ecological health can be restored with minimal effort and 2.) Lands supporting locally rare or listed threatened and endangered species. Consult with Planning & Development staff in order to suggest greenways and links between preserves. Provide expertise and advice to the President and Executive Director with regard to purchasing critical lands supporting rare or endangered species, or regionally rare plant communities such as fens or seeps. Reintroduce natural conditions and environmental forces/factors that favor proliferation of native species. This would include disabling drain tile systems and/or routinely conducting prescribed burns. Consult with Executive Director, Planning staff and President to create macro-site size preserves.
