1  The assessment unit

For this example we will focus on one Macrogroup, the 1.A.1.Ei.563 - Guajiran Seasonal Dry Forest.

1.1 Unit description

The current description of this macrogroup is available in NatureServe Explorer:

Summary

This macrogroup includes seasonally dry deciduous to semi-deciduous forests distributed along the Caribbean coast of Colombia and Venezuela and inland, surrounding Lake Maracaibo in Venezuela and also on the foothills of Sierra Nevada de Santa Marta and the Perija range in Colombia, usually growing on alluvial-colluvial lowlands between sea level and 500 m elevation, depending on the location. They can attain a relatively complex, multi-layered structure with a dense canopy or, in the dry end of their gradient, have a more open canopy and less strata. In general those growing in the upper elevations have more moisture available (from precipitation and fog).

Characteristic species

Characteristic species from sub-humid to dry forests are Cordia panamensis, Swartzia pinnata, Ocotea glandulosa, Hura crepitans, Cedrela odorata, Carapa guianensis, Roystonea olerace, Anacardium excelsum, Calycophyllum candidissimum, Brosimum alicastrum, Trophis racemosa, Simira klugii, Belencita nitida, Centrolobium paraense, Maytenus karstenii, Melicoccus bijugatus, Gustavia tejerae, Eugenia oblongifolia, Myroxylon balsamum, Triplaris lindeniana, Machaerium spp., Tabebuia chrysantha, Tabebuia serratifolia, Tabebuia heterophylla (= Tabebuia pentaphylla), Trichilia pleeana, Allophylus racemosus (= Allophylus occidentalis), Trophis racemosa, Eugenia mcvaughii, Acacia glomerosa, Lochocarpus punctatus, Coccoloba fallax, Guazuma ulmifolia, Enterolobium cf. cyclocarpum, Morisonia americana, Bursera graveolens, Ficus prinoides, Sabal mauritiiformis, Bactris minor, Bourreria cumanensis, Erythroxylum cumanense, Brownea penduliflora, Bauhinia multinervia (= Bauhinia megalandra), Senna bicapsularis (= Cassia emarginata), Calliandra caracasana, Inga punctata, Erythrina poeppigiana, Platymiscium diadelphum, Guaiacum officinale, Cochlospermum vitifolium, Jacquemontia cumanensis, Stenocereus griseus.

Distribution

It is distributed between Colombia and Venezuela in South America, and Trinidad and Tobago in the Caribbean.

1.2 Assessment results

For the assessment in Ferrer-Paris et al. (2019) there are results for a global (i.e. continental) assessment considering the whole distribution, as well as for country or national assessments that consider only the portion of the distribution in each country. Tables for each assesment are created using functions from Chapter 9.

Global

Overall this macrogroup is considered Endangered based on A3.
