Management of Edge Habitats Ryan Pankau NRCS Forester Murphysboro, Illinois Ryan.Pankau@il.usda.gov USDA is an equal opportunity provider and employer. Helping People Help the Land John Groninger Forestry Professor SIU Carbondale Groninge@siuc.edu
2
Outline Types of edge Assessing your edge – Making a plan Common issues in edges Management solutions and NRCS Practices Management Example – The Groninger Farm
3
Woodland Edge Defined as the transition zone between maturing forest and adjacent habitats.
4
Induced – caused by human activities such as agriculture, timber harvest, or development. Constantly changing. Types of Edge Inherent – created by natural divisions such as soil type, topography, etc. Tend to be relatively stable.
5
Types of Edge Forest meets grassland Forest meets cropland Forest meets forest Forest meets water Tree spp meet other tree spp So IL pine stands Effect of scale
6
Defining Edge Habitat Think about these differences: Mature forest meets grassland Pure pine stand meets mixed pine stand Plum thicket meets tallgrass prairie Bunch grass clumps meets bare ground between clumps Scale matters to wildlife spp of concern Differences in habitat structure within a given cover type may not qualify as edge
7
Assessing Your Edge Habitat and Making a Plan
8
Assessing Your Edge Define Management Objectives/Goals Wildlife habitat and species of concern Timber resources Aesthetics and recreation Soil and water conservation
9
Assessing Your Edge Survey and inventory your edge habitats Plant composition, structure, age class, etc Erosion issues Area/length of edge compared to other habitats How much edge do you want/need?
10
How much edge is enough? More edge = More wildlife Not always true! Highly dependent on wildlife management objectives, species of concern Consider degree of Forest Fragmentation in your area
11
Forest Fragmentation Some ground nesting birds are negatively impacted by edge. Edge may make it easier for predators to raid nests.
12
Who can help plan? IDNR District Wildlife Biologists District Foresters NRCS Field Offices servicing every county Consulting Foresters
13
Common Issues in Edges Invasives Erosion Management
14
Edge is Dynamic Dynamic nature of Edge Habitats poses management challenges High light promotes a greater variety of plant spp Location is often a high traffic area Humans and wildlife Constantly fighting plant succession
15
Management of Edge
16
Aspects of Management What are some of the things we can manage? Plant structure Plant diversity/species composition Physical layout of edge Erosion control
17
More edge or less? Don’t take out existing forest to gain edge. Take advantage of such programs as CRP to expand or create edge. Your goal should be to expand the edge while helping or buffering the existing woods.
18
Aspects of Mgmnt Plant Diversity and Species Composition Plant Structure Stem Density
19
Den trees Leave at least one den or “wolf” tree per acre of edge.
20
Maintenance You will have to cut or mow to maintain this area, highly dynamic Fall burns can also improve habitat if done correctly and safely. Be aggressive when dealing with invasive species such as honey suckle and garlic mustard.
21
Low-Contrast vs. High- contrast edges
23
Wildlife tree and shrub spp American Hazelnut American Plum Dogwood Species Red Bud (Winter Hardy?) Serviceberry Other species
24
NRCS Practices Filter Strip Edge Feathering Tree and Shrub Planting Forest Stand Improvement Riparian Buffers
25
Management Example -The Groninger Farm-
27
Groninger Farm 12.4 acres of forest 6.4 acres of cropland 3,100 ft. of edge habitat
28
Edge Habitat 3,100 Ft.
29
Avoid Straight lines Non native species Corn and soybeans don’t make good edge species.
30
Wildlife Brush Piles Woody material constructed to furnish additional escape, nesting, resting or winter cover for wildlife Readily available material from Intermediate Forest Management Practices Several strategically placed or well dispersed medium- size piles are more beneficial than one large one Living brush piles can be constructed by hinge cutting 3-5 small hardwood saplings towards a center-point and amending with limbs and brush Foundation is important for cavities and longevity Large material on bottom allows for a hollow core and keeps smaller limbs off the ground to help prevent decay.

Equal Opportunity The U.S. Department of Agriculture (USDA) prohibits discrimination in all its programs and activities on the basis of race, color, national origin, age, disability, and where applicable, sex, marital status, familial status, parental status, religion, sexual orientation, genetic information, political beliefs, reprisal, or because all or a part of an individual's income is derived from any public assistance program.
