CIFOR-ICRAF s’attaque aux défis et aux opportunités locales tout en apportant des solutions aux problèmes mondiaux concernant les forêts, les paysages, les populations et la planète.

Nous fournissons des preuves et des solutions concrètes pour transformer l’utilisation des terres et la production alimentaire : conserver et restaurer les écosystèmes, répondre aux crises mondiales du climat, de la malnutrition, de la biodiversité et de la désertification. En bref, nous améliorons la vie des populations.

CIFOR-ICRAF publie chaque année plus de 750 publications sur l’agroforesterie, les forêts et le changement climatique, la restauration des paysages, les droits, la politique forestière et bien d’autres sujets encore, et ce dans plusieurs langues. .

CIFOR–ICRAF publishes over 750 publications every year on agroforestry, forests and climate change, landscape restoration, rights, forest policy and much more – in multiple languages.

CIFOR–ICRAF addresses local challenges and opportunities while providing solutions to global problems for forests, landscapes, people and the planet.

We deliver actionable evidence and solutions to transform how land is used and how food is produced: conserving and restoring ecosystems, responding to the global climate, malnutrition, biodiversity and desertification crises. In short, improving people’s lives.

Analysis of composition and density of soil seed banks of Prosopis juliflora in Afar region rangelands, Northeast Ethiopia

Exporter la citation

• We analyzed the composition and spatial variations of soil seed banks of plant species and densities of soil seed banks in Prosopis juliflora invaded and noninvaded grasslands. • Soil samples were collected from soil layers of 0 to 3, 3 to 6, and 6 to 9 cm. • The highest density of 1,037 ± 633 seedlings/m2 was recovered from a soil depth of 3 to 6 cm. But, the lowest density of 461 ± 315 seedlings/m2 was recovered from the depth of 0 to 3 cm. • In noninvaded grasslands, the lowest density of 94 ± 32 seedlings/m2 was germinated in the soil depth of 0 to 3 cm. In Prosopis juliflora grasslands at the 3 to 6 cm, the density was 519 ± 257 seedlings/m2, but 1,484 ± 1,144 seedlings/m2 was in the noninvaded grasslands at the depth of 3 to 6 cm. • Our findings have implications for recovery of rangelands after disturbances.
