Field Reports

Because time and resources are limited, it is important that SLELO-PRISM partners focus the management of invasive species on sites that are  considered ecologically important and/or sites that are considered to have conservation value. In addition, sites that are considered to be seed banks, vectors or that pose a proximity threat to high value sites are all factors involved in determining site-based management on both public and private lands. The SLELO partnership has named these sites as Priority Conservation Areas or PCA’s.

We are currently conducting work across 24 PCA’s. The PCA’s are then further divided into Highly Probable Areas (HPA’s).

HPAs include those areas where human activities or site conditions increase the probability of an invasive species becoming established. Conditions and activities at these HPAs may facilitate invasion in several ways, like human movement through the area, disturbances caused by concentrated human activities and site conditions. Some examples for HPAs in aquatic areas include boat launches, fishing access sites and coves with shallow slow moving waters. HPAs in terrestrial areas include trailheads, parking areas, campgrounds and disturbed areas from logging or other events.

Below you will find an update for each PCA we are currently working in based on the field reports that have been conducted in these areas since 2013. There are additional species that we have focused our survey and treatment efforts on, which are also reported here. Additional details from field reports and other management efforts can be found on individual  pages.
