Land Fragmentation
Beck Sinclair, Jessie MacQueen, Courtney Phillips

2. Background
"Habitat reduced from its original extent to a series of smaller patches or fragments" (Glennon and Kretser, 2005)
Can occur via geological processes or human practices
Land fragmentation = habitat fragmentation
Highgate Gorge

3. Edge Effects
Differences in the environmental and biotic conditions between edge and interior habitats

4. Major Human Causes Development Roads Agriculture Timber Harvest
Developments being named after the habitat that they destroy...
Roads are as frequent as streams in the US ecosystems
Burlington Free Press: Beaver Patrol

5. Purpose Statement
To determine the risk of land fragmentation within the watersheds of the Lake Champlain Basin.
LCB broken into three regions (NY, VT, and Quebec). Each region has different laws regulating land fragmentation and development.

6. Effects Filter Source Effect Importance Agriculture 1 2 Dams 0.5
Fisheries
Forested Areas
Industrial
Marinas
Roads

Wastewater Treatment Plants

7. Sources with Known Effect
Agriculture
Roads
Urban
Industrial
Lorax - industry of "thneed" production gave the Swomee Swans sore throats, reduced the Bar-ba-Loots food source

McNeil Generating Plant

8. Sources with Unsure Effect
Waste Water Treatment Plants
Dams

9. Sources with No Effect
Marinas
Fisheries

10. Impacts Filter Habitat Impact Importance Agriculture 1 Developed Area
Forest 2
Herbaceous
Lake Champlain < 6ft
Lake Champlain > 6ft
Other Lakes/Ponds
Rivers/Streams
Wetlands

11. Impacted Habitats Wetlands Forest Agriculture Herbaceous
Agriculture as an impacted habitat is due to pollination effects

12. Unsure Impacted Habitats
Other lakes/ponds
Rivers/Streams
Developed Area
Ask ENSC 202 Class
Developed area positively impacted. More is formed.

13. Non-impacted Habitats
Lake Champlain <6ft
Lake Champlain >6ft
Water sources are not effected by LAND fragmentation. This was assessed by another group
Uncertainty? Should aquatic habitats be included
Champ is not affected by land fragmentation because we did not look at aquatic habitat fragmentation.

14. Future Recommendations
Focus on aquatic habitats
Economic values effecting importance filter
Break up developed/urban source into more specific categories
Research zoning laws – is protection enough?
