shallow soil valleys<br />

There are a few<br />
micro-sites of pools<br />
in bush-l<strong>and</strong><br />

characterized by bush<br />
forming shrubs, lianas <strong>and</strong><br />
climbers with few trees<br />
<strong>and</strong> associated emergent.<br />
There are clustered<br />
populations of Sorindeiamadagascariensis<br />
Plants which can tolerate<br />
water soaked muddy soils.<br />
In Ngezi this is referred to<br />
as Raphia palm. Other<br />
swamp populations include<br />
Typhonodorum<br />

species)<br />
Erica bush-l<strong>and</strong> forms a<br />
loose canopy 5m high. Few<br />

The mangrove formation<br />
occurs as open st<strong>and</strong>s,<br />
rarely close on shore<br />
between low <strong>and</strong> high<br />
water mark. Most have<br />
pneumatophores or are<br />
viviparous. Smaller<br />
patches occur around the<br />
bay of Tondooni peninsula<br />
Nymphaea, Sedges <strong>and</strong><br />

Harungana, Syzygium <strong>and</strong><br />
Parinari separate the two<br />
swamps<br />
