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 />
