Hi! I’m a fairly new environmentalist and member of iNaturalist and would appreciate and ideas or advice for how to approach this subject. I am trying to find a way to compare which invasive plants most greatly contribute to a loss of bio-diversity in my town. I have documented close to a hundred sp…

in the US, the worst invasive weeds are usually listed on federal and state noxious weed lists. here’s the Massachusetts Prohibited Plant List: https://www.mass.gov/service-details/massachusetts-prohibited-plant-list .

Interesting and difficult question. An idea would be to select one expected effect (a variable linked to loss of biodiversity) and measure it along the time. For example: you may want to consider the idea of “competition with native plants”. For that you can select a number o alien species and meas…

I am doing research on exactly this topic. I compare the diversity (including its multiple aspects) of grassland patches invaded by different invasive plants and uninvaded patches. This approach is called space-for-time substitution because I suppose that close sites have a similar background and di…

usually, noxious weeds are determined based on some sort of risk assessment. here’s an example risk assessment by USDA for Hydrilla: https://www.aphis.usda.gov/plant_health/plant_pest_info/weeds/downloads/wra/hydrilla-verticillata.pdf , and here’s the generic USDA risk assessment framework: https://w…

i suggest you collect some data! Find some areas infested by each weed and log all other species you find on or directly under them. Use tags or annotations to sort them, and you can really start to see patterns. For instance, in Vermont i have observed that Glossy Buckthorn usually has way more na…

Thanks! I’ll definitely look at that. Do you have any suggestions for comparing multiple plants that are on that list?
