What is the jungle like?
Jungle substrate varies
greatly from river to river. Some rivers have trees with a high canopy
adjacent to the river's edge. In these areas, one can walk about
in the jungle with little effort. Other rivers have extremely impenetrable,
thick low-lying brush along the rivers edge. In all cases,
vegetation changes the further one travels from the water's edge.
The jungle floor also varies from place to place. Some jungles have
smooth sandy bottoms with a light covering of leaves, while other locations
have spongy bottoms consisting of several feet of intertwined roots and
dead leaves.
During the dry season, when we fish for peacock bass, the river systems drop within their bank structure, leaving the rainy season floodplain high and dry. This seasonally flooded region contains relatively low botanic diversity, typically 20 or so flood-tolerant species per hectare. These regions are known as "igapo" in blackwater systems ("varzea" in white water rivers). They tend to be actively fruiting and flowering during the rainy season and are essentially dormant during the dry period when anglers fish for peacock bass.
At the edges of the floodplains (and usually accessible at points along the typically meandering rivers that we fish) the forest is called "terra firme". This is where visitors can visit the high primary forest with its incredible botanic diversity (as many as 400 tree species per hectare). Here is where the jungle giants may tower 250 feet above the ground.
The high gradient rivers that cascade from mountainous regions such as the "Guyana Shield" in northern Brazil are typically lined with "gallery forest". Relatively diverse, these regions are not normally subjected to extended flooding like that inundating the igapo regions. Consequently these rivers have a unique flora, quite different from the lowlands river.
Most rivers allow access to a variety of jungle
and forest types along their banks, from floodplain jungle to primary forests.
Guides will be happy to take you exploring in the forest if you're interested,
but don't wander off by yourself. Hiking in the jungle without an
extremely knowledgeable guide is not recommended - it is very easy to get
lost. |
