Natural History

Southern Marsh Orchid

SOUTHERN MARSH ORCHID, LOCALLY COMMON, BUT THREATENED BY OVERGRAZING OR LOSS OF WET MEADOW HABITAT
The river and river valley provide a wide range of habitats: management work needs to be directed at sustaining this diversity without favouring one set of species to the exclusion of others: the general loss of watermeadows and overshading of watercourses, and general changes in the management of farmland in the valley present particular challenges in the different world of the twenty-first century.

In addition, water quality and flow problems (on the Southern Wey catchment most prevalent on the Slea tributary) have introduced new problems of habitat change and instability; alien introductions, from mink to pondweeds to balsam all pose threats (or the reality) of species loss and require new approaches to management.

 

Native Crayfish

NATIVE CRAYFISH: NOW SURVIVING MOSTLY IN SMALL POCKETS ON THE WEY, OUT-COMPETED AND INFECTED BY ESCAPED COMMERCIALLY REARED AMERICAN CRAYFISH
Nonetheless, the rivers and streams of the Southern Wey catchment still offer a rich and diverse environment for water and wetland flora and fauna.
