<strong>Serengeti</strong> National Park <strong>General</strong> <strong>Management</strong> <strong>Plan</strong><br />

36<br />

1.3.2-3<br />

The Riverine Forest is ranked as being the most threatened from fire, with the potential that<br />

it could be eliminated throughout the <strong>Serengeti</strong> within the 10-year period of this GMP. There<br />

are two different types of broad-leaved Riverine Forest within SENAPA (Bayona and<br />

Sharam, 2001), under various degrees of threat as described below:<br />

� The first forest type grows along the tributaries of the Mara River. This forest is characterised<br />

by an open canopy of Euclea, Diospyros, Otea, and Croton species. This forest is<br />

rapidly being replaced by grassland, with a loss of 75-85 percent in the past 25 years.<br />

� The second forest type grows along the Orangi and lower Grumeti rivers. This forest is<br />

composed primarily of species derived from central Africa. Its canopy is composed<br />

largely of Lecaniodiscus, Eckebergia, Zziphus, and Ficus species. This forest appears to<br />

be relatively stable compared to the Mara Riverine Forests, having decreased in size by<br />

25-35 per cent in the past 20 years.<br />

The threat from fire to the Acacia and Terminalia woodland is ranked according to the type<br />

of fire. The hot late-season fires pose the greatest threat and have the potential to seriously<br />

degrade the woodlands throughout the <strong>Serengeti</strong>. The “cool” fires are less severe a threat to<br />

the woodlands and are expected to only moderately degrade the woodlands on a localised<br />

basis.<br />

Kopje habitat is inherently fire resistant and therefore fire only poses a low threat. However,<br />

little is known whether fire is an important factor in their ecology. The ranking of the threat for<br />

the next 10 years identifies a moderate level of degradation (medium severity) of kopje habitat<br />

on a localised scale (low scope).<br />

This management target will address the threats to these four habitats, which in turn will address<br />

the fire threat to the natural habitat for the Black rhino Conservation Target. Threats to<br />

the Migration from early dry season fires, relate to the availability of dry season grassland<br />

forage, and are therefore dealt with separately.<br />

The management actions designed to address these threats and enhance the conservation<br />

status of the habitat Conservation Targets are as follows:<br />

Action 1.3.1: Prioritise critical habitats and areas for fire protection within the Riverine<br />

forest, Acacia woodland, Terminalia woodland and Kopje habitat<br />

SENAPA does not have the financial or personnel resources to actively protect against fire<br />

across all four habitats. Instead sensitive, representative and important areas within these<br />

habitats will be selected for concentrating efforts in fire management, as identified in the<br />

SENAPA Fire <strong>Management</strong> <strong>Plan</strong>.<br />

Action 1.3.2: Identify and preserve adequate areas of dry season forage for migrant<br />

species<br />

Within SENAPA there are critical areas of forage that need to be preserved to support the<br />

Migration. The critical dry season forage includes areas in the north of SENAPA, including<br />

Kogatende, Lamai, Nyamalumbwa, Bologonja, Tabora B and Ndasiata. The critical early dry<br />

season forage includes the western corridor and central SENAPA.
