dc.description.abstractAvocado (Persea americana Mill.) is an important commodity with substantial global growth in semi-arid regions under irrigation, such as Central Chile. This region of Chile has faced severe drought that has resulted in the abandonment of avocado orchards, previously established in a global biodiversity hotspot. This study investigates the early effects of abandonment of avocado farms on vegetation recovery and soil after severe droughts. We measured and characterized early plant successional processes by identifying the flora, vegetation coverage, similarity, and soil characterization through 42 transects distributed in four recently abandoned sites, a productive farm, and a natural site. Multivariate analysis was used to identify significant relationships between soil and habitat properties and vegetation abundance and coverage variations for the dominant species. The Jaccard similarity coefficient was used to compare sites. The establishment of native or endemic species was extremely limited and variable between sites. In total, we recorded 55 vascular plants (49.1% were native). The results indicated that Schinus molle L. has become a dominant colonizer, particularly in highly disturbed planting rows in abandoned farms. Factors such as the sources of S. molle propagules, soil salinity, and organic matter accumulation were identified as key predictors of its coverage and presence in abandoned farms. The study concludes that the abandonment of avocado farms, coupled with severe drought, has created favorable conditions for the recruitment of this species, adversely impacting other native species. This research underscores the importance of considering the remaining features of soil and habitat in new successional processes in highly disturbed areas.
