“…In addition, tree cover had a negative association with bamboo density and thus on the generation of new sprouts. Tree shade was associated also with smaller stem diameters (as previously indicated by Bitariho and Mosango, 2005). Since tree shade appears to have a negative effect local clearing of all competing vegetation, including other bamboo, might similarly reduce competition and stimulate sprout production (though this is not clearly observed in the harvesting data).…”

“…Before MGNP became a protected area local people exploited the forest's wild bamboo: larger stems were used for construction, thin stems for bean stakes, old stems for fuel, and young stems for basketry (see also Bitariho and Mosango, 2005). All such use has been prohibited since 1992.…”

“…Montane bamboo grows gregariously within most mountain forests of tropical Africa and Asia (Wimbush, 1945; Kigomo, 1988; Bitariho & Mosango, 2005). It is a tropical high altitude woody grass of the family Poaceae and subfamily Bambusoideae (Kigomo, 1988; Bystriakova, Kapos & Lysenko, 2004; Bitariho & Mosango, 2005). The bamboo has recently been described taxonomically as Yushania alpina K. Schumann (Embaye, 2000; Bystriakova et al.…”

Previously it was taxonomically described by several authors as Arundinaria alpina , Synarundinaria alpina and Sinarundnaria alpina (Wimbush, 1945; Kigomo, 1988; Scott, 1994; Bitariho, 1999; Bitariho & Mcneilage, 2004; Bitariho & Mosango, 2005). In Uganda, the bamboo occurs in Bwindi, Mgahinga, Rwenzori and Mt Elgon National Parks and Echuya Central Forest Reserve.…”

Montane bamboo is of immense importance to the people living adjacent to Echuya Forest Reserve. It is used for building poles, bean-staking and basket weaving. The bamboo in Uganda occurs mostly in protected areas. Over the past 50 years, the bamboo forest cover has been declining. This study aimed at determining bamboo density and distribution and the possible causes of its decline within Echuya. We used exploratory inventories, bamboo assessment plots and village interviews to determine bamboo population structure and possible causes of its decline in Echuya. Bamboo forest decline in Echuya may be blamed on several factors that interplay together. Poor harvest methods especially during the clear cutting of bamboo for bean-stakes and stakes for house wefts seems to be the remote cause of the bamboo forest decline. Other causes for the bamboo forest decline are damages caused by insect borers and climber loads on the bamboo stems. The remote causes have been exacerbated by the invasion of secondary forest tree species such as Macaranga kilimandscharica that have slowly taken over areas previously occupied by the bamboo forest. Seventy per cent of the local people interviewed agree that over-harvesting of bamboo is the major reason for its decline.Key words: bamboo strata, Echuya forest, montane bamboo RésuméLe bambou de montagne est extrêmement important pour les gens qui vivent près de la Réserve Forestière d'Echuya. Il sert à faire des charpentes, des tuteurs pour les haricots et des paniers tressés. En Ouganda, le bambou pousse surtout dans les aires protégées. Les surfaces occupées par les bambous ont décliné depuis 50 ans. Cette recherche visait à déterminer la densité et la distribution des bambous et les causes probables de leur déclin à Echuya. Nous avons réalisé des inventaires exploratoires, des plots pour l'évaluation des bambous et des interviews dans les villages pour déterminer la structure des populations de bambous et les causes du déclin. Ce déclin peut être attribué à plusieurs facteurs interactifs à Echuya. Des méthodes de récoltes malencontreuses, spécialement lorsque les gens font des coupes à blanc pour des perches à haricots ou la charpente des maisons, semblent une raison ancienne du déclin de la forêt de bambou. D'autres causes sont les dommages causés par les insectes térébrants et par le poids de ceux qui marchent sur les jeunes pousses. Les causes anciennes ont été exacerbées par l'invasion d'espèces d'arbres de forêts secondaires comme Macaranga kilimandscharica qui ont peu à peu gagné des zones occupées auparavant par la forêt de bambou. Soixante-dix pour cent des personnes interrogées ont reconnu que la surexploitation du bambou était la raison principale du déclin constaté.

Changes in floristic composition, diversity and anthropogenic perturbations in an east African tropical forest

We assessed changes in floristic composition, diversity and anthropogenic activities in an East African forest; Echuya Central Forest Reserve (ECFR). Using 272 permanent sample plots, comparisons between 2015 and 2021 were made. Twenty‐two tree species were recorded with Macaranga capensis being the most dominant. Tree species density increased significantly from 152 stems/ha in 2015 to 306 stems/ha in 2021. Similarly, trees basal area increased significantly from 19 m2/ha in 2015 to 38 m2/ha in 2021. The bamboo stem density decreased significantly from 11,931 stems/ha in 2015 to 1807 stems/ha in 2021. Shrubs, lianas, vines and herbs' densities did not show significant differences between 2015 and 2021. Furthermore, a number of human activities significantly increased from 22 activities per hectare in 2015 to 83 per hectare in 2021. The Non‐Metric Multidimensional Scaling (NMDS) ordination shows that the human activities with the strongest impact on tree species composition and basal areas were fuelwood collection, human trails, livestock grazing and pole cutting. In conclusion, ECFR is floristically poor; secondary forest tree species are replacing the bamboo forest and human activities could be negatively affecting the ECFR flora. We recommend interventions of increasing people's livelihood incomes to decrease their dependence on forest resources.
