Determining The Existence Of White-Clawed Crayfish
The White clawed-Crayfish population has dramatically declined because of pollution, competition and disease transferred by non-native species. Due to the protection afforded to them, White clawed-Crayfish Surveys may be required if distribution and historical records suggest they may be present within the watercourse in your site or on adjacent land. At JCA our surveys will determine if White clawed-Crayfish are present and whether the proposed works will adversely affect the species. For example, for informing management plans of monitoring the effectiveness of habitat management based on indicator species. Terrestrial invertebrate surveys are often needed on ecologically sensitive sites. Aquatic invertebrates are often required to monitor water quality, particularly if construction work causes runoff.
The majority of ecological surveys are seasonally constrained. Use our ecology survey calendar to plan your project timetable and factor in any seasonal constraints to project timescales as early as possible to prevent any delays.
