4.1.7.4 Monitoring indicators and regimes<br />
The indicators and regimes will be monitored indirectly through, water quality changes, soil erosion<br />
levels and plant species diversity change. Any environmental changes must be observed and<br />
reacted upon.<br />
4.1.8 Discussions<br />
<strong>Lake</strong> Nakivali wetland as a representation of <strong>Lake</strong> Mburo-Nakivali system is highly degraded due<br />
to human activities. Natural vegetation has been cleared for farming. This might be partly due to<br />
overpopulation, poverty and lack of enforceable policies and reasonable management measures.<br />
According to Sisk et al. (1994); McCracken and Abaza (2001); and Reynolds and Smith (2002)<br />
ecosystem degradation phenomena are a worldwide environmental problem limiting the ecosystems<br />
sustainability. Seriously damaged lands not only lose control over resources, but also lose the<br />
capacity for self-repair and are unable to prevent additional degradation. As these degrading<br />
processes continue, a threshold can be crossed exceeding the ability for the ecosystem to recover<br />
and desertification results, a dynamic and self-perpetuating process. There is need therefore to<br />
restore this ecosystem. This restoration will bring back native species and their habitats. Seedlings<br />
of many species are expected to emerge, survive and establish reproducing populations, and then<br />
populations are expected to assemble into a community similar to the original system. Species<br />
composition can reflect the process of vegetation succession and be used as one of the objectives<br />
of vegetation restoration and improvement.<br />
4.1.9 Conclusions and recomendations<br />
The different degradation treatments had significant effects on species composition, plant cover and<br />
species diversity, and thus affect the ecological function of plant communities. Therefore, decisions<br />
and regulations related to strategies, such as re-vegetation planning, species selection, seedling<br />
management should be carefully considered. Reforestation with native dominant plant species<br />
or natural restoration is a reasonable choice for reforestation. A landscape approach should be<br />
condidered for community mobilization, awareness programmes and restoration of various zones.<br />
