“…Hence, the more land a household owns, the higher the chance is to grow more trees in their land. e finding of this study is in line with Giday et al [52] and Aklilu et al [53] who reported that tree species richness increases as farm size increases. Asfaw and Hulten [54] and Abebe [41] also reported a positive relationship between farm size and tree species richness per farm and a similar relationship between wealth status and farm size in Southern Ethiopia.…”

Agricultural intensification is a major challenge for biodiversity conservation in many parts of the world. Organic agriculture is perceived as a possible solution for biodiversity conservation in agriculture dominant systems. This study aimed at investigating the current status of plant species diversity and its determinants in organic agriculture-dominated areas of Gedeo zone, Southern Ethiopia. Multistage sampling procedures were used to obtain 108 households from three agroecological zones of the study area, and plant species data were collected from the quadrants laid in farms of sampled farmers. Besides, diversity management practice data were collected using focus group discussion. A total of 234 plant species belonging to 82 plant families were identified. Most (69.2%) of species in the system were native. The mean value of richness and Shannon index evenness for the whole system was 10.36, 2.06, and 0.89 for highland midland and lowland agroecological zones, respectively, which is relatively high compared with other agriculture-dominated systems in the tropics. The diversity of overall plant species were significantly affected by both agroecological zones and the wealth status of farmers. Midland and lowland agroecological zones had the highest richness values for total plant species than highland. Similarly, highest richness was recorded among farmers of rich and medium wealth classes than poor. The diversity of tree species was significantly affected by both agroecological zone and wealth status of farmer households. The lowland agroecological zone had a significantly higher number of tree species than midland and lowland agroecological zones, while the rich farmer had higher tree diversity compared to medium and poor farmers. The study also identified that diversity of shrubs were significantly influenced by agroecological zone. The midland agroecological had a significantly higher number of shrubs diversity compared to lowland and highland agroecological zones. In this study, herbaceous species diversity was not influenced by both agroecological zone and farmer wealth class. The function of plant species and indigenous plant species maintenance practice had its own effect on plant species diversity in the study area, since the area is dominated with organic agriculture. Therefore, to maintain the current status of the system and to improve the farmer’s livelihood, development planners may need to design agroecological-based plant species conservation strategies that give due consideration for indigenous plant species conservation practices and function of plant species.

“…The result also showed that HHs within the rich wealth class has a larger average area of the home garden as compared to the HHs in the medium and poor wealth classes (Table 5). Giday Kidane et al(2019) and Mebrate Abiyot et al (2021) reported a positive relationship between farm size and tree species richness per farm and a similar relationship between wealth status and farm size in southern Ethiopia.…”

This study was conducted to investigate the farmers’ tree growing practices and diversity of tree species in the home garden,farmlands, and nearby forest areas of Abaychomen District, Eastern Wollega, Oromia region, Ethiopia. Data were collected fromsampled Households (HHs) using purposive random sampling methods for the socio-economic survey and a systematic sampling technique for vegetation assessment.For the interview, 152 HHs were selected from the two Peasant Associations of Gutene and Dinoberema. Focus group discussions and site observations were used. The result showed 51 tree species in Dinoberema and 41 in Gutene were identified and recorded. The Shannon diversity index is high in the natural forest of both sites and low in the crop fields of Gutene and home garden area of Denoberema. Simpson diversity index exhibited a similar trend as the Shannon diversity index in both sites. Croton macrostachyus and Podocarpus falcatus are the 1stand the 2ndmost important tree species in both sites.Higher Sorensen coefficient similarity observed between crop field and home gardens. The result also revealed, HHs within the rich wealth class have a large area of home garden related to medium and poor. According to respondents viewed, (80 % observed labour availability) in Gutene and (60% observed land availability) in Dinoberema were opportunities to grow trees. However, shortage of cash and land were the main constraints for tree growing practices.Therefore, this study is important for effective tree biodiversity.Hence, identifying and documenting the tree species diversity and practices of local peoples on tree management are necessary to build the gaps in knowledge

“…Trees have impressive potential to improve soil fertility and forbid soil erosion in land management like farmland and watershed management [58][59][60][61]. For example, benefits of farmland woody plant species in the case of Northwestern Ethiopia are tremendous and soil fertility enhancement and management role indicates 35.14% among other benefits [62].…”

A woody plant functional trait that directly affects its fitness and environment is decisive to ensure the success of an Agroforestry practice. Hence, recognizing the woody plant functional traits is very important to boost and sustain the productivity of the system when different plants are sharing common resources, like in Agroforestry system. Therefore, the objective of this paper was to understand how woody plant functional traits contribute to sustainable soil management in Agroforestry system and to give the way forward in the case of Ethiopia. The contribution of woody plant species in improving soil fertility and controlling soil erosion is attributed by litter accumulation rate and the season, decomposability and nutrient content of the litter, root physical and chemical trait, and spread canopy structure functional trait. However, spread canopy structure functional trait is used in coffee based Agroforestry system, while with management in Parkland Agro forestry System. Woody species of Agroforestry system added a significant amount of soil TN, OC, Av.P, K, Na, Ca, and Mg nutrients to the soil. Woody plant species of Agroforestry system and their functional traits are very important to ensure sustainable soil management. Thus, further investigation of the woody plant functional traits especially the compatibility of trees with cops is needed to fully utilize the potential of woody species for sustainable soil management practice.
