Is there a regeneration crisis? SEEA Species Accounts for Adansonia digitata in Benin: Implications for Africa
by Fadeke Ayoola, FCCA
30 April 2026
Abstract
This pilot study evaluated whether natural regeneration can sustain the existing Adansonia digitata population through the end of this century. The study examined the species’ spatial distribution, population structure, and regeneration status across Benin, West Africa. This national‑scale approach enabled a comprehensive assessment of how rainfall variability, agricultural expansion, and protected‑area coverage influence the species’ current and future viability.
Using 300 georeferenced citizen‑science photographs representing individual trees, the study applied the System of Environmental‑Economic Accounting (SEEA) Species Accounts framework—specifically stock, condition, reproduction, pressure, and ecosystem accounts—to produce the first experimental SEEA species account for A. digitata. Spatial data processing and species distribution mapping were conducted in QGIS 3.44.11, while Python 3.14, implemented through Visual Studio Code, supported data organisation, analysis, and visualisation.
The pilot study demonstrates that SEEA Species Accounts, combined with citizen‑science observations, offer a standardised, cost‑effective, and spatially explicit method for monitoring population status, regeneration dynamics, and long‑term conservation prospects of culturally and ecologically important tree species. These results provide a strong foundation for a full‑scale investigation into the regeneration capacity and future persistence of Adansonia digitata in Benin and across Africa.

A Pilot Assessment of Data Strengths and Gaps SEEA Species Accounts for Adansonia digitata in Nigeria.

Abstract
This study assesses whether existing data can support a pilot System of Environmental-Economic Accounting (SEEA) Species Account for Adansonia digitata (African baobab) across Nigeria. Three complementary categories of data were evaluated: spatial data, biological data, and inventory and population data. Of these, spatial data were considered the most robust. A reconnaissance survey involving 400 participants was conducted, alongside spatial analysis of 91 baobab and 129 Eidolon helvum observations sourced from iNaturalist. Remote interpretation of geotagged photographs was also undertaken to develop a SEEA Species Account-aligned account and assess temporal patterns from 2012 to 2025.
The findings indicate that the population is dominated by mature trees (95%), with very few saplings (5%) and no recorded seedlings, suggesting a regeneration deficit that current monitoring systems have not captured. Spatial distributions were highly fragmented, and overlap with pollinators was inconsistent. However, the limited volume and uneven timing of observations restrict confidence in interpreting potential reproductive risks. Seasonal clustering of citizen-science records highlights potential phenological patterns but also reveals prolonged periods without monitoring coverage. Overall, the evidence base is too sparse, inconsistent, and biased to support high-confidence ecological assessments.
The study demonstrates that SEEA Species Accounts provide a structured mechanism for integrating diverse data sources and identifying weaknesses in existing monitoring systems. However, without substantial improvements in field surveys, regeneration assessments, and systematic phenology monitoring, data gaps will continue to undermine the long-term management of the species. Strengthening monitoring through annual SEEA Species Accounts, quarterly phenology surveys, and periodic landscape audits is essential to building a reliable evidence base for the conservation and sustainable management of Adansonia digitata in Nigeria, with implications for the wider region.
