“…Unfortunately, the worst-case scenario did come to the tropical island of Maui, HI, this past August. Invasive buffelgrass blankets the mountainsides, especially on the seasonally dry, windswept west side of the island, spreading as a weed on defunct sugar plantations and former pasture lands ( 11 ). When fire sparked in the hills above Lahaina, strong winds fanned the flames through dry buffelgrass and down into town.…”

“…Engott, 2007). In more recent years, due to changes in the economy, plantations have largely been abandoned (Zou and Bashkin, 1998), and former plantation land is now primarily dominated by invasive grasses such as guinea grass ( Megathyrsus maximus , Farrant et al, 2023). These land-use changes are a significant conservation concern because alien species often invade native communities after some type of disturbance (Smith, 1985).…”

PremiseCompetition from non-native species and habitat loss are common threats to biodiversity and may act synergistically to increase competition for decreasing habitat availability. We develop a workflow using Hawaiian dryland ferns as a model for the interactions between land-use change and non-native competition in determining available habitat for native species.MethodsWe use fine-resolution climatic variables and carefully curated occurrence data from herbaria and community science repositories to estimate the distributions of Hawaiian dryland. We quantify the degree to which non-natives occupy similar regions of niche space and map the remaining available habitat given land-use change in Hawai‘i.ResultsThe estimated niches for the endemic species (Doryopterisspp.) are more narrow than for the indigenousPellaea ternifolia.Doryopteris angelicahas the lowest proportion of non-native occurrences in its estimated suitable area whileD. decorahas the highest. BothD. decoraandD. decipienshave low proportions (¡20%) of inferred suitable area covering native habitat.DiscussionAreas characterized by shared environmental preferences of native and non-native ferns may also decrease due to human development and fallowed agricultural lands. Our study demonstrates the value of a novel ecological niche modeling approach for conservation risk assessment in a rapidly changing and urbanized island ecosystem.

PremiseCompetition from naturalized species and habitat loss are common threats to native biodiversity and may act synergistically to increase competition for decreasing habitat availability. We use Hawaiian dryland ferns as a model for the interactions between land‐use change and competition from naturalized species in determining habitat availability.MethodsWe used fine‐resolution climatic variables and carefully curated occurrence data from herbaria and community science repositories to estimate the distributions of Hawaiian dryland ferns. We quantified the degree to which naturalized ferns tend to occupy areas suitable for native species and mapped the remaining available habitat given land‐use change.ResultsOf all native species, Doryopteris angelica had the lowest percentage of occurrences of naturalized species in its suitable area while D. decora had the highest. However, all Doryopteris spp. had a higher percentage overlap, while Pellaea ternifolia had a lower percentage overlap, than expected by chance. Doryopteris decora and D. decipiens had the lowest proportions (<20%) of suitable area covering native habitat.DiscussionAreas characterized by shared environmental preferences of native and naturalized ferns may decrease due to human development and fallowed agricultural lands. Our study demonstrates the value of place‐based application of a recently developed correlative ecological niche modeling approach for conservation risk assessment in a rapidly changing and urbanized island ecosystem.
