are written descriptions for each site that include the degrees of quality and rarity, site ranking on

The information presented in the Erie County Natural Heritage Inventory, last updated in 2012,
will be used to guide and focus efforts of the Lake Erie Watershed - Cooperative Weed
Management Area. By identifying the unique and rare habitats within the watershed, the CHNI
has provided an extremely valuable tool enabling the LEW-CWMA to prioritize and direct
limited resources to preserving, enhancing, and restoring the ecological integrity of these sites.
Determining Sites
Initial site evaluations documented in the Inventory and Monitoring section of this plan are
essential to determining the highest priority invasive species management locations within the
Lake Erie watershed. Prioritization of these sites will be based upon the pool of existing data as
well as data collected each season regarding invasive plant communities present and the
ecological sensitivity of each site. While taking into account existing information such as the size
and severity of the infestation, site accessibility, ownership, and available resources, the steering
committee will be responsible for choosing a minimum of five sites for inventory each season
and a minimum of three target locations for management. An additional factor for site selection
is the locations proximity to other treatment areas. There is an increased benefit in building upon
successful control areas and expanding invasive treatments outward from the initial control site.
When sites have been chosen for inventory, the LEW-CWMA coordinator or other CWMA
member will be responsible for contacting the property owners and natural resource managers,
providing relevant background information regarding the negative impacts of invasive species as
well as the groups mission. The primary goal of working with these landowners and land
managers is to establish working relationships and promote stewardship long into the future.,
Members of the CWMA will work to conduct a property-wide invasive plant inventory, draft a
management plan, and work directly with the landowner or natural resource manager to
implement the plan as resources are available.
After property inventories are complete and management plans have been developed, the
steering committee will meet to discuss the findings and determine which sites are the best
candidates for management and restoration efforts. Site specific plans will outline the
management timeline and goals for each site, target species, known locations and approximate
size of each infestation, as well as the dates and level of success for each treatment.
Understanding that invasive species will be present to some degree in all locations, this review of
available information will allow partners to determine where the limited resources that are
available will have the greatest impact. When possible, restoration efforts that include the
eradication of early detection and rapid response species should be given high priority.
Understanding that management efforts in most locations will require multiple treatments over
an extended period of time, the LEW-CWMA will consider all factors including existing funding
