Hi everyone!
At Willistown Conservation Trust (WCT), EnviroDIY sensor station data are informing our land management and restoration practices.
The Trust’s two EnviroDIY sensor stations are positioned up- and downstream of a riparian restoration project – a 5-acre lake bed composed of unconsolidated legacy sediments and lacking any riparian buffer, which will be replanted with trees. Before installing the sensor stations, we applied for funding to support this riparian planting through the PA Department of Conservation and Natural Resources (DCNR). The proposal adhered to the DCNR’s recommendations for regular herbicide application both in site preparation and long-term planting maintenance.
However, once the EnviroDIY sensor stations were installed, we gained a deeper understanding of our stream reach and the surrounding lake bed, forcing us to reconsider this herbicide-heavy management plan.
Between April and December 2018, the EnviroDIY sensor stations recorded 24 overbank floods – floods that otherwise may have gone undetected! Not only is our stream reach prone to flooding, but as the stream overflows its banks, the flood water spreads out across the flood plain and the meadow returns to a lake, with low velocity water pooling across the entire five acres.
With these data in hand, we met with the DCNR to discuss the terms of our planting proposal. We shared with them our concerns that rigorous herbicide application at our planting site could be dangerous; based on the EnviroDIY data, which suggests that our site is prone to unpredictable and frequent flood events, we feared these chemicals could wash into the stream, threatening aquatic life.
The DCNR agreed with our assessment, siting the EnviroDIY sensor station data as a powerful and convincing argument for altering herbicide use from our planting management plan. Our new proposal has significantly minimized herbicide applications with increased manual maintenance and features fewer but larger trees to withstand the frequent flood events.
