Work parties will continue through October.

·       Created a guide describing the plants in the Native Plant Demonstration Garden for visitors.

·       Assisted with the communication and coordination of non-native invasive plant removal adjacent to homeowner properties.

·       Gathered water samples from Yellow Lake for testing of possible pollutants that could pose a threat to aquatic life and surrounding vegetation. Specific tests included: petroleum hydrocarbons, metals, coli forms and nitrates. Tests were conducted by AM Test Labs and results showed.

·       Met with an Environmentalist from EarthCorps Habitata and Science Department to discuss the overall health and restation progress of Klahanie’s major NGPAs. The survey results were very positive and are available for review at the office.
