Use wire fencing to exclude large native herbivores Forest Conservation

A replicated, controlled study in 2005-2008 in temperate forest in France (Pellerin et al. 2010) found no effect of excluding deer browsing on species richness and diversity of trees and herbaceous species. The number of woody plant species (deer exclusion: 8-10; unfenced: 7-10/m2) and their species diversity (Shannon's index deer exclusion: 2.1-2.5; un-fenced: 1.9-2.1) and the number of herbaceous species (exclusion: 17-20; un-fenced: 13-17/m2) and their species diversity (Shannon's index deer exclusion: 3.4-3.5; unfenced: 2.9-3.1) were similar between treatments. Data were collected in May 2008. At one site there were 60 sampling plots (1 m2) inside a 1 ha fenced area (deer exclusion) and 60 similar plots inside a 1 ha open area (unfenced). At a second site there were 42 sampling plots (1 m2) inside a 1.5 ha fenced area (deer exclusion) and 42 similar plots inside a 1.5 ha open area (unfenced). Both sites were regularly grazed by roe deer Capreolus capreolus and red deer Cervus elaphus. Exclosures were set up in March 2005.

 

Remove woody debris after timber harvest Forest Conservation

A replicated, controlled study in 2005-2008 in temperate forest in France (Pellerin et al. 2010) found no effect of clearing of woody debris on species richness and diversity of trees and herbs. Numbers of woody plant species (control: 7-8; cleared: 10 m2) and diversity (Shannon's index control: 2.1-2.5; cleared: 1.9-2.1), and number of herbaceous species (control: 17-20; cleared: 13-17 m2) and diversity (Shannon's index control: 2.9-3.5; cleared: 3.1-3.4) were similar between treatments. Data were collected in May 2008 in 60 pairs of control (woody debris left) and 60 cleared (woody debris cleared of) plots (1 m2) in one site, and 42 similar pairs at a second site. Plots were set up in May 2005.
