The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 640 records.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Area of Mediterranean Central Chile, with extension to the semi-dry coastal desert and template forest. In locations, from Copiapó to Chillan

To assess the ecological effect of Vachellia caven across its Southern American distribution, we recorded in 17 locations in Chile the woody species regenerating in mixed forest or matorral where the scope species is commonly present.

|Study Area Description||Distribution of Vachellia caven in South America, across Chile. These include Mediterranean climate, with xeric and temperate plant communities|
The personnel involved in the project:
Between 10 to 15 Vachellia caven trees (replicates) were selected in each location, and in all, we recorded the woody species regenerating. These include from seedlings, saplings to mature plant, under the whole area of the crown projection (canopy). For assessing differences in the plant communities regenerating, we also made the same procedure in a contrasting condition. For this, we selected 10 to 15 random outside areas in each location. Outside areas were close to the previous V. caven tree, around 20 m to avoid its shading effect. Each outside area corresponds to contrast for a given V. caven tree.
|Study Extent||The 17 locations were sampled in one day each. All records were taken before 2019 rainfall events, to prevent seasonal regeneration.|
Method step description:
- All recorded species were identified in field or through photos for posterior identification in lab. We did not take samples of the identified species to avoid neglecting effects on the regeneration. All individuals regenerating were height measure and corresponding abundances per species/condition/replicate can be requested to the author.
