  abstract = {{B}iological invasions are a leading cause of the ongoing biodiversity crisis, and particularly so on islands. {H}owever, the role of invasive alien plants ({IAP}s) as a driver of native plant declines and extinctions remains unclear. {T}he inherently slow and gradual nature of plant extinctions, especially that of long-lived woody species, could be a reason. {H}ere, we examined temporal trends in subpopulations of 28 threatened endemic tree ({TET}) taxa. {W}e questioned the frequency with which they decline in association with {IAP}s on {R}eunion {I}sland ({S}outh{W}est {I}ndian {O}cean), and asked whether the most susceptible {TET} taxa exhibit characteristics that could reveal the underlying ecological mechanisms. {W}e resurveyed 182 historically described subpopulations and tested whether observed trends of juvenile and adult {TET}s correlate with the abundance in {IAP}s using path analyses, while distinguishing {TET} taxa with respect to their leaf-height-seed characteristics and extinction risk. {T}he trend of adult {TET}s was not affected by {IAP}s but that of juvenile {TET}s was negatively correlated with the abundance of {IAP}s in the understory layer. {T}his was particularly the case for {TET} taxa with conservative resource-use strategies (low specific leaf area or low maximum height), whose juveniles might be particularly susceptible to competition with {IAP}s, but not for {TET} taxa with large seeds, whose metabolic reserves make seedlings more likely to attain a critical size. {T}hese findings suggest that {IAP}s can significantly contribute to the extinction dynamics of trees, primarily by limiting regeneration through competitive exclusion, and that their impacts vary depending on the traits of the affected taxa.},
