Invasive Species Monitoring

Invasive Plants

Since 2014, TTCD has conducted annual invasive plant surveys along roadsides, airstrips, private properties, industrial worksites trails, and stream crossings in Tyonek, Beluga, and Shirleyville. Surveys have also been conducted in Skwentna (2014) and Alexander Creek (2014-2016).


Due to the negative impact of pike on salmon populations and the lack of data on pike’s extent within the watershed, TTCD’s goal is to determine the extent of pike and develop a control plan on priority populations and waterbodies. Since 2015, TTCD has conducted annual pike derbies in Beluga and Tyonek to collect data on pike locations.
