Current Management

During the planning process there is a moratorium on any substantive development.  However, the following management activities are ongoing: 

Trail Network

An access trail network has been developed. The route from Main Street to the large pond and around the pond is relatively cleared and can be accessed wearing street shoes or by bicycle. The remaining trails have been brushed out but may be partially blocked by blackberry regrowth. Hand pruners and appropriate footwear is recommended on these trails. Note: the trails near the streams may be flooded during the winter months. Also, be alert for poison oak.

Aquatic vegetation Control

The "weed" in the large pond is known as "Water Shield" a common native aquatic plant (Brasenia schreberi). We are working with the Center for Lakes and Reservoirs at Portland State to find the best treatment option. Click links below for more information.

Note that mechanical removal is effective and we have been doing that on a limited scale. Feel free to join us!

Current Blackberry Management

BB Manage Areas

The pond property was idle for over thirty years and became severely overgrown with blackberries.  The current goal is to control the berries on the level ground areas. Repeated mowing in the areas shown appear to repressing the regrowth. 

Vegetation Inventory & Management

A detailed inventory of the vegetation on the west side of the pond is being implemented by Wendy Stevens, a local landscape architect / botanist.

Inventory & Management Recommendations

Nutria Control

Nutria (see image) is an invasive rodent that, since the 1970's has been severely affecting the integrity of the pond dikes, water quality and local ecology. The nutria population has been significantly reduced through trapping and habitat modification (Nutria Control Report). Maintenance trapping is being done on a as-needed basis.  Please do not disturb the live traps.

Dike Repair

The integrity of the dike on the large pond has been compromised by nutria / beaver activity that occurred during the thirty years that the property was closed and unmanaged. (Dike Repair

Flood Control

Beaver dams in the west side stream system have the potential to cause backwater to develop in the 4th St culvert located on Eagle Valley Road. This condition reduces the stormflow capacity of the culvert, resulting in flooding in the immediate vacinity. This condition can be aleviated by manually adjusting the heights of the beaver dams on an as-needed basis (Flood Issue Report).

Annual Costs

Estimated annual costs for current level of management. Current funding has been with grant funds that is not sustainable over the long term. Volunteer labor, if available, can reduce the costs substantially.

Budget
