ELM Management Plan Calendar Year 2002

 

I. Introduction

 

The Fermi Laboratory Director established the Ecological Land Management Committee (ELM) to oversee and facilitate the restoration of available lands. In accordance with this objective, the ELM Committee manages available areas of the site as per principles of ecosystem management and restoration, in the effort to maintain and build biological diversity, conserve natural resources and increase the site’s aesthetic appeal.

 

The 6800-acre Fermilab site is divided into management tracts as shown on the CY 2001 Fermilab Land Management Map, which is updated annually to reflect changes in land usage. These tracts are defined by current land use practices and habitat diversity:

 

• Technical Area (TA) tracts are committed exclusively to the high-energy particle physics mission     of the Laboratory

• Agricultural (AG) tracts are leased for agricultural use

• Recreational Area (RA) tracts support non-programmatic, recreational purposes

• Residential (R) tract refers to the residential area in the Village

• Ecological Land Management (ELM) tracts enhance the natural resources of the Laboratory.

 

Tract boundaries are meant to be dynamic and should change with management needs and ecological considerations.

 

This plan shall address the management of only those tracts available for restoration—ELM—and shall not interfere with the current or future mission of the Laboratory. The plan is intended to provide a long-range coherent vision for development, not set management priorities or propose year-to-year activities.    

 

Each year the Committee reviews the accomplishments of the current calendar year and advises the Laboratory Director of prioritized activities for the next year. This advice, once approved by the Director, informs the activities of the more specific and detailed Annual Plan. 

 

Only minor changes to this general plan may be made at this point without approval of the Director. The ELM Committee may make recommendations for ecological management of areas outside the scope of this plan and should take the following restrictions into consideration:

 

• Changes in Agricultural tract boundaries need the Director’s approval.

• Management of the on-site lake shorelines must be coordinated with FESS.

• Recommendations for management of the lake bodies (e.g. stocking or fishing and/or water return ditches and the berms (e.g. cover species) shall be made to the Director.

 


II. ELM Accomplishments 2001

 

A summary of the Laboratory’s ELM activities is listed below. Specific tract accomplishments are detailed in Section IV of this plan.

 

A.     New Prairie

Approximately 15 acres of new prairie were planted on the MI Stockpile in ELM 4.  The planting of this new prairie with Little Bluestem and Sideoats Grama is part of a program to develop short-grass areas and encourage the nesting of grassland birds. If the Little Blue Stem thrives as hoped, it will become a valuable seed-collecting source for the site.

 

B.     Agricultural Leases

325 acres were added to Agriculture.  This new lease includes half of the RA-2 (hayfield) tract (AG-8), which shall be rotated with the other half of RA-2 through a three-year “land management AG License” program.

 

C.     Enrichment

1.      ELM tracts 1, 16, 24, 25 and 26 were broadcast seeded with an enrichment mix.

 

2.      65 new trees and bushes were planted in ELM 24 during the 2001 Arbor Day activities. Species included shagbark hickory and bur oak.

 

D.    Prairie Seed

1.      Total seed collected

 A total 85 forb species were hand collected by lab personnel and volunteers.

2.      Harvests

a.      Volunteer Harvest

Round-headed bush clover, obedient plant and nodding wild onion, among other species, were collected from the Main Ring tracts.  Spiderwort, Golden Alexanders, and Culver’s Root were collected along the Burlington Northern Railroad.

 

b.      Machine Harvest

More than 8,000 pounds of prairie matrix seed were collected via machine harvesting in ELM tracts 24 and 25.

 

c.       Summer Intern

A Roads and Grounds summer intern, Jennie Rudderham, collected many early and mid-summer prairie species that are rarely collected.  Collected species include Pedicularis canadensis (prairie betony), Hypoxis hirsuta (yellow stargrass), Sisyrinchium albidum (blue-eyed grass), Polygala senega (Seneca snakeroot), Panicum leibergii (panic grass), Phlox pilosa (prairie phlox) and Phlox glaberrima (marsh phlox), Lobelia spicata (pale spike lobelia), Zizia aurea (golden alexanders), Carex bicknellii (Bicknell’s sedge), Anemone canadensis (meadow anemone), Allium canadense (wild onion) and Tradescantia ohiensis (spiderwort); and trace amounts of Comandra richardsiana (false toadflax), Dodecatheon meadia (shooting star), Heurecha richardsonii (alum root), and Galium obtusum (wild madder).

 

Jennie also collected understory woodland plants such as Hydrastis canadensis (goldenseal), Trillium grandiflorum (large-flowered trillium) and Lithospermum latifolium (broad-leaved puccoon); Stipa spartina (porcupine grass), a dry prairie species; and various sedges and rushes from wet prairie and wetland areas.

 

d.      Other Prairies

Dr. Betz collected seed of Zizia aurea (golden alexanders) and Cacalia plantaginea (prairie Indian plantain) from the Hinsdale prairie.  He also collected trace amounts of Dodecatheon meadia (shooting star) and Heurecha richardsonii (alum root). 

 

3.      Trades

Forb seed was received from Kane County, and Will County in exchange for combined bulk seed.

 

E.     Noxious Weed Control

As part of the noxious weed control program, Roads and Grounds personnel sprayed teasel in ELM tracts 1, 4, 5, 9, 19, 20, 21, 24, 25 and 26; AG tracts 3, 4 and 7; and TA tract 1. Loosestrife control was conducted in ELM tracts 1, 10, 11, 15 and 24; buckthorn and honeysuckle in ELM tracts 24 and 25; and cottonwood in ELM 1. Oriental bittersweet in ELM tract 24 and TA tract 1 and poison hemlock in ELM tracts 21 and 23 were also sprayed.

 

The Roads and Grounds department does not have the resources to effectively manage the spread of these invasive exotics.

 

F.      Prescribed Burns

Fermilab’s request for a waiver of the DOE Moratorium on Prescribed Burning was approved.  The Roads and Grounds department conduced burns in ELM 24 and ELM 25

 

G.    Status of Flora

Robert F. Betz (See Botanical Report-Fermilab 2001) prepared the annual status report of flora on-site. 

 

H.    Status of the On-Site Bird Populations

Peter Kasper prepared the annual report on the on-site bird population, 2001 Fermilab Bird Report. Peter Kasper also maintains the on-going compilation of bird observations since 1987, The Birds of Fermilab.

 

I.       Status of Butterflies at Fermilab

The compilation of butterfly observations for the past three years may be seen at Butterfly Observations.  Tom Peterson prepared the third annual report on a survey of the butterflies on site, Butterfly Report to the ELM Committee - Fermilab - 2001.

J.      Deer Management

During the period from October 2000-March 2001, 21 white-tailed deer were removed from Fermilab.  This represents a maintenance level of management.  Based on a series of spotlight counts conducted in the spring of 2001, the Laboratory has set a goal of removing an additional 68 individuals during the 2001-2002 permit period.

L.     Other Accomplishments/Special Projects

1.      Butterfly Website

A summer intern, Rory Parilac, worked with Liz Quigg and Tom Peterson to present his butterfly data into a child-friendly website format. Welcome to Fermilab's Butterflies features a butterfly search engine and a guide to observing butterflies.

 

2.      Frog Survey

Beginning in the Spring 2001, Fermilab participated in the Chicago Wilderness sponsored “Calling Frog Survey”.  Data on frog species presence will be added to the regional herpetological atlas, which is maintained by Chicago Wilderness for our region.  The survey was limited to three areas located in ELM 1, 24 and 27.  In 2002, the survey will be extended to include areas in ELM 14. 

 

Species reported for Fermilab for this year were Rana clamitans (green frog), Rana catesbiana (bull frog), Bufo americanus (American toad), and Pseudacris triceriata (chorus frog).  Other species noted at the Lab, but not surveyed are Hyla chrysoseles (Cope’s gray tree frog), Pseudacris crucifer (spring peeper), and Rana pipiens (Northern leopard frog).

 

3.      Frog Website

Rory also created a Frogs at Fermilab website with a general description of frogs, provided by Rod Walton, and pop-up descriptions of the 8 species commonly found at the Laboratory.   

 

4.      Plant Search Database

Three summer interns (Jennie Rudderham, Rory Parilac, and Caleb McKinney) updated the Fermilab Plant Search database, adding more than 300 photos.

 

M.  Community Participation

1.      National Public Lands Days

For the third year, Fermilab registered its first fall volunteer harvest as a National Public Lands Day’s event.  Chicago Wilderness sponsors National Public Lands Day.  The event was cancelled due to September 11 events which impacted access to the site.

 

2.      Volunteer Harvest

Over 100 people participated in the one fall prairie harvests. The first fall harvest was canceled due to the tightened security measures from 9/11.

 

3.      Third Thursday Clean-ups

On the third Thursday of good-weathered months, Roads and Grounds organizes a volunteer clean-up at the Laboratory.  This year saw inbound and outbound Pine Street, prairie plot 12 along Kirk Road, and the shorelines of Swan Lake and the Reflector Ponds cleaned during employee lunch hours.  Participation ranged from 10 to 25 persons for each clean-up.

 

4.      Arbor Day

Approximately 125 people turned out for Arbor Day plantings.

 

5.      Seed Exchange and Donation

Seed trades conducted so far this year include 2 garbage bags of prairie matrix to Spencer Cortwright of the Little Calumet River Project in Indiana, 1 bag of matrix to Lisa O’Brian of Red Gate High School in St. Charles, and 5 bags to Ron Panzer for enrichment of a new area at Markham Prairie. Six bags of prairie matrix was donated to St Charles Park District. Two additional schools received small amounts for their study areas.

 

6.      Christmas Bird Counts

The annual spring and Christmas Bird Counts were organized and conducted on site by members of the DuPage Birding Club. The results may be viewed at Christmas Bird Count.

 

7.      Eagle Scout Projects

2 martin houses were installed—one at Casey’s Pond and one at Logo Lake.

6 bat houses were installed—three at Site 29 and three at Site 58.

Park benches constructed for Big Woods trail.


 

III. ELM Recommendations 2002

 

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 underway. 

 

The following recommendations involve activities, other than routine Roads and Grounds maintenance and improvements, that will further the long range goals established by the ELM Committee.

 

A.     Habitat Development

1.      Maintain Oxidation Pond Water Elevation at 717.0 Feet

The elevation at the bottom of the Oxidation Pond is 716.5 feet, and the boards in the A.E. Sea discharge structure are set at 718.0 feet. The Committee supports a management strategy for the A.E. Sea/Dusaf Pond that would maintain the water level at 717.0 feet. The resulting seasonal fluctuations above and below this level would allow significant improvement and development of a quality wetland in the Oxidation Pond after removal of the berm.  In the interim, the Committee recommends the Oxidation Pond be pumped alternate years to maintain water elevations at or below 717.0 feet.

 

2.      Burn Eastern Half of ELM 14 Prior to 5/1/2002

The Bell’s Vireos were breeding in this area again this year and were found in both the burned and unburned sections.  The Committee recommends that the eastern half be burned Spring 2002.  The birds that use this area arrive in early May, so the burn should be done well before then.

 

3.      MI Stockpile

The Committee recommends that the Main Injector stockpile be enriched with native seed.

 

4.      Mensing Farm

The Committee recommends that this area be developed as a new picnic space.

 

5.      Eola Rd. Grassland

Henslow’s Sparrows returned to the site again this year, suggesting that our policy of mowing in August is having a beneficial impact on the habitat.  However, the Committee recognizes the need to remove isolated trees in the area, as most grassland birds will not nest within 50 yards of a tree.  The new land management sub-committee will evaluate tree removal and make recommendations.

 

6.   Remove noxious invasive trees and brush around Meson Hill if time permits.

 

B.     Management Programs

1.      Experimental Sites for Threatened Plants

The Committee recommends the Lab consider whether establishing “Experimental Sites” for some threatened plants would introduce a special burden if the operational needs of the Lab dictated construction at that site.  Currently, the committee recommends that such populations not be introduced into the site due to the approval cycle with the Fish and Wildlife Service that could possibly seriously curtail proposed construction programs should they impact a threatened plant .

 

2.      Tree Removal

Many places on site have an increasing population of “undesirable” trees—e.g. cottonwood, box elder and buckthorn.  In the southern part of ELM-1, parts of ELM-6 and other locations scattered across the site, the number and size of these trees is negatively impacting the higher quality prairie development; and in the MI wetland mitigation area of ELM-4, numerous small cottonwood trees need to be removed because of their potential impact on the physics program.

 

The Roads and Grounds Department removes these aggressive trees as their schedule permits and as directed by the Committee.  These trees may be encroaching on prairies or wetlands or may be in other areas of the site producing an undesirable seed source.

 

 

C.     Laboratory Relations

1.      Prairie Seed Agreements

The Committee encourages the on-going attempt to develop working relationships with commercial prairie seed vendors. This relationship may take the form of seed trade or “special AG land licenses”.

 

2.      Research

The Committee continues to encourage the Lab to seek and participate in ecologically related research compatible with the Lab Ecological Land Management Program. The Committee also encourages the Lab to continue to seek interested individuals to conduct ecological surveys. For example, Tom Peterson’s Butterfly Survey Program and the Chicago Wilderness sponsored “Calling Frog Survey” are significant additions to the annual surveys being done on-site.

 

The Committee also recommends that NERP projects be updated and contacts made with questionable old projects.

 

3.      Eagle Scout Projects 

Two new Eagle Scout projects are underway.

 

4.      Prairie Reconstruction Video 

Work continues on the script and the collection of relevant video footage.

 

D.    Miscellaneous

• Remove the cyclone fence from both sides of the road in ELM 24.   Almost done.

• Backfill the chlorinator tank adjacent to the Oxidation Pond.

• Basal treat noxious trees in ELM 1 (Main Ring). Ongoing.

• Basal treat noxious brush on EJ&E remnant prairie.

• Install grass waterways in agriculture fields.
