Fermilab Annual Ecological Land Management Plan
for Calendar Year 1999
I. Introduction
The Annual Ecological Land Management Plan lists the most significant accomplishments during the period October 1997 through December 1998. The second part of the plan offers recommendations for a coherent, priority set of activities for Calendar Year 1999, which incrementally advances the goals in the Long-Range Ecological Land Management Plan. The Committee makes these recommendations with the suggestion that the resources which the Lab can make available for ecological land management be applied to these activities. It is understood that the judgment of those doing the work will prevail on the details of implementation and that changes in scope and detail will occur. The Committee would like to be informed of significant changes during the regular meetings.
Attached to this report is a copy of the Fermilab Land Management Plan Map for reference. The map has been updated to include the names of the lakes and show changes in the horse trails.

III. Ecological Land Management Accomplishments from October1997 through December 1998
Activities conducted throughout the site are summarized and listed below. The attached ELM Tract Annual Management Plan Sheets detail accomplishments in each ELM tract.
A. Harvests
B. Tracts Enriched
C. New Prairie Planted
About 20 acres of new prairie were planted in ELM 10. About 6 acres were planted in ELM 22 to establish a low-maintenance base. About 35 acres of prairie were planted in ELM 26 west of the MI berm.
D. Ongoing Improvement Programs
E. Status of Flora and Fauna
The project to control the deer population on-site began operation during the last part of 1997. USDA sharpshooters, accompanied by Lab personnel, conducted operations in February and March of 1998. Operations began again in November of 1998 and will continue until March of 1999. The goal for this period is to make a substantial reduction in population, and come closer to the ultimate goal of a herd that is in equilibrium with the entire ecosystem.
Peter Kasper maintains a Web site (http://www.fnal.gov/ecology/wildlife/list.html) that contains a great deal of information about the bird life at Fermilab.
This year the most notable changes in terms of breeding species was the increase in the number of Bell's Vireos nesting in ELM 14, which has developed into ideal habitat for this species. This was also the second year in which a Yellow-Throated Vireo nested in the Education Center canal area. A pair of Upland Sandpipers returned to ELM 16, but whether they bred successfully is unknown. Short-Eared Owls have also returned to this area this winter, which demonstrates that the current mowing schedule has not negatively affected them.
The resident Canada Geese had poor breeding success again this year; however, numbers of migrant/wintering geese are as high as ever. Interestingly, there seems to be a much larger proportion of the small "cackling geese" races than normal. There are also a lot more Snow Geese than usual.
This year's bird migration was characterized by a very poor spring migration for woodland birds with record low numbers of warblers and thrushes being found. The fall migration, however, was considerably better, with low water levels on Lake Law and Main Ring Lake attracting many shorebirds including a new species for the Lab. Three new species were added to the Fermilab bird list this year, bringing the current tally up to 265.
Status of Flora at Fermilab
There are 254 native prairie and prairie marsh species and 192 native tree and shrub species found at Fermilab. In addition, there are 118 species of non-native (exotic) herbaceous weeds and 30 species of non-native trees and shrubs. In total, there are approximately 600 species. Most, but not all, of the non-native species are confined to roadsides, ditches, berms, and other disturbed areas.
New Species
The first prairie was planted at Fermilab over 20 years ago. Each year the established prairie has been enriched with seed from most species of prairie plants known to be native to this area. Thus, most of the expected species are already present and very few new native species are expected to be found. However, two new native species were found in 1998. A small colony of one-flowered broom rape was discovered in the prairie along the Burlington-Northern railroad. This is a relatively rare plant, a root-parasite without chlorophyll. The second new find was the fringed gentian; a few plants were observed in a low area along Pine Street in ELM 25.
Non-native plants find abundant opportunities in the conditions unfavorable to the native plants. Thus, we expect to find new small, non-native, nondescript plants along salt-contaminated roads, in trampled ground around buildings, and in disturbed areas around new construction. The garden heliotrope, a garden ornamental that occasionally escapes cultivation, was the only non-native species found in 1998. It was discovered in the brushy disturbed area of ELM 14.
Prairie Plant Populations Changes
There has been a noticeable increase in the populations of second stage prairie plants during the last few years, especially during 1998. In ELM 1, the area of earliest restoration, significant population increases were seen in the following species:
| round-headed bush clover | mountain mint |
| false dragonhead | nodding wild onion |
| prairie coreopsis | wild quinine |
| rattlesnake master | lead plant |
| purple and white prairie clovers | marsh phlox |
| yellow star-grass (an amaryllis) | golden Alexanders |
| blue eyed-grass (an iris) | prairie dropseed grass |
In ELM 26 there was a continued increase in the populations of rattlesnake master and in the tall, spectacular blue blazing stars. Increases in these two species were also noted in ELM 1. There was a noticeable increase in populations of three of the four gentians found at Fermilab: stiff gentian in ELM 1 and in ELM 25; closed gentian in ELM 1 and ELM 25; and yellow gentian in ELM 26.
Populations of the Eurasian teasel and Purple Loosestrife have been brought under control by Roads and Grounds. Careful monitoring of the tall and aggressive common reed found in ditches and roadsides at Fermilab should continue. It is likely to become a problem and will need to be controlled.
Status of Marshes
The prairie marshes continued to show increased populations of bulrushes, spike rushes, sedges, monkey flower, fog fruit, horehounds, and various mints. Small colonies of the impressive cardinal flower are cropping up in a number of marshes in ELM 1 and in ELM 25. Enrichment efforts have been successful in increasing populations of the two native marsh grasses: prairie cord and blue-joint grasses. The larger amount of grass will give increased fuel-load with concomitant better burns. More intense fires will better control woody vegetation along marsh edges and stimulate increases in the populations of other marsh plants.
Status of Woods
In contrast to the prairies and marshes, the ground cover in the woods has been severely degraded by deer. The remaining ground cover is dominated by the non-native garlic mustard that is not grazed by deer. Results at Fermilab and elsewhere indicate that burning is helpful in controlling this noxious weed.
The observed recovery of the ground cover within the two exclosures, which were fenced five years ago, offers hope for improvement if the deer population is brought under control. In the meantime, non-native woody plants are slowly being eliminated by the cutting and use of herbicides. This will open up woodland edges and allow for the influx of native woody plants.
Status of the Buffalo Herd
Fermilab has maintained a herd of Bison on site since 1969. Last spring 35 calves were born. Fermilab maintains the herd size between 40 and 50 breeding animals. Typically, most of the calves, and sometimes older animals are sold by sealed bid each fall.
F. NERP Research Projects
Two of the four projects listed as ongoing last year are still underway.
Studies by Younger and Weis have been completed.
Of the three new projects listed last year, two have been completed, and one is ongoing.
The project by Vihnanek has been completed. This was part of a study to quantify fuels/biomass on sites in various ecosystems.

H. Community Participation
Granger Middle School children were on-site three days doing volunteer work. This included about 70 students helping with cleanup and planting activities. A large contingent of Wheaton Warrenville High School students put in a full day of hand-harvesting seed.
Fermilab hosted the Illinois Native Plant Society Annual Meeting. About 200 people from throughout the state attended the one-day meeting.
Fermilab exchanged prairie seeds with the DuPage, DeKalb, Kane, Will, and Kendall Forest Preserve Districts. The city or park districts of DeKalb, St. Charles, Kankakee, and Village of Sleepy Hollow also participated in seed exchanges. The exchange program included Argonne Lab, Cantigny, Elmhurst Prairie, Hinsdale Prairie, Indian Boundaries Prairie, West Chicago Prairie Steward Group, Fox Valley Land Foundation, Fox River Water Reclamation District, Openlands Project, and the Red Oak Nature Preserve.
Seed was donated to 17 area schools, (including 4 high schools, 5 junior highs, and 8 elementary schools) and to 7 other municipalities, soil and water districts, etc.
IV. Recommendations for Calendar Year 1999
The Committee believes that the first priority must be the ongoing maintenance and improvement activities (e.g., mowing, burning, enrichment, redistribution of small trees, and spraying of herbicides) conducted by the Roads and Grounds personnel. These activities are critical to maintaining and building on ecological improvements already achieved. The recommendations below are activities, in addition to maintenance activities, which will further the long-range goals already established.
A. Special Projects
The Committee recommends the following special projects, some of which are already planned.
B. Recommendations for each ELM Tract
Specific recommendations for each ELM tract are indicated on the ELM Tract Annual Management Plan Sheets which follow. The second column is copied from the Long-Range Management Plan. The third column is a copy of the FY 98 Plan. The fourth column indicates what was done in that tract during the period October 1997 through December 1998. The fifth column contains the Committee recommendations for CY 1999. The recommendations are based on what the Committee believes is the next logical step in moving toward the long-range goal, tempered with the Committee's estimation of what resources may be available during the year.
