Session: : Using Ecology to Future-proof Invasive Plant Management

INS 8-2 - Using weeding experiments to test if non-native plants are inhibiting forest regeneration in nature reserves and parks in Singapore

Tuesday, August 8, 2023
1:30 PM – 3:00 PM PDT
Location: 251
We describe a collaboration between researchers and reserve managers to ride on an on-going invasive species management programme to test if non-native plant species are really drivers of ecosystem impacts or simply ‘passengers’ of past or ongoing disturbance. Preliminary results showed that weeding improved native seedling survival and recruitment. However, recruitment diversity was dispersal-limited. In addition, re-invasion occurred which suggests the necessity of planning for re-weeding. This relatively simple pilot project has the potential to be scaled up and to incorporate elements of community engagement and citizen-science in order to educate the broader public about invasive species management.
