Ecological Succession In the Hawaiian Rain Forest Bare Rocks Journey to a Beautiful Tropical Rain Forest

By Riley Mill Science 10 November 27, 2013

Bare Lava Rock Welcome to Hawaii! This is Bare lava rock, cooled lava from a volcanic eruption and can be frequently found in hawaii. At At this this part part of of Hawaii succession there is no plants or animal growing on or around the bare lava rock.

Stage info: Soil: Non-existent Species diversity: None Trophic levels: None Niches: None Nutrient recycling: Minimal

Primary Succession Stage 1: Pioneer Species

Soil: Little soil and no life in it Species Diversity: None yet, only lichen is growing Trophic Levels: Lichen, 1 producer Niches: Simple, lichen brakes down rock Nutrient Recycling: Minimal

Lichen! Lichen is a pioneer species that grows on rocks, as the lichen grows they eat away at the rock and brake it down to make soil, the dead lichen makes good nutrients for plants and animals to start growing there

Primary Succession

Stage 2: Early Colonizers

Early colonizers! Mosses, fungi, mushrooms, worms, flowers, and grass have arrived to help make bigger plants and animals live there. They make the dirt rich and more fertile, and make more habitats for future animals.

Soil: Thicker and more life living in it species diversity: Low, few insects and plants trophic levels present: Not many niches: Few, and simple

Primary Succession Stage 3: Opportunists

Opportunists! This is when more animals like birds, frogs, and lizards start to move into the developing mature Rain Forest, these animals and plants make the soil and forest good enough for other larger animals can settle there. The forest is beginning to bloom with life

Soil: full of insects, pretty deep species diversity: Medium, no large animals or predictors have settled yet Trophic levels present: Few-Many no Big threats Niches: Few animals and plants that help fertile the forest and complete the Trophic Levels Nutrient Recycling: Many

Primary Succession

Stage 4: Mature Forest/Climax Community

Feral Pig [invasive species!]

The Rain Forest is climaxed!

The trees have developed and have made a thick canopy covering the forest underneath from the sun. This Rainforest now has many beautiful Animals, Insects, Reptiles, Trees, Flowers and Aquatic Animals now that cover all trophic levels.

Soil: Full of life, and deep. Species diversity: Large, more then 1000 species Trophic levels present: Complete 4 Trophic Levels Niches: Many, Extremely Complex Nutrient recycling: Rich, extensive, and complex


Describe your disturbance here

Disturbance in the Hawaiian Rain Forest! A volcanic Eruption has happened and burned the Rain Forest. Every plant and Animal has been affected some how, But the Rain Forest has a Thick Canopy to help protect It's best from everything being Destroyed

Soil: Still full of life, still deep Species diversity: Not as large as before but still super large Trophic levels present: All 4 trophic Levels Niches: Extremely Complex Nutrient recycling: Extensive, complex.

Secondary Succession

Secondary Succession Takes place! Secondary Succession is Much quicker then primary succession because the soil is still rich and there is still seeds left from previous plants, and some animals are still alive.

Soil: Deep and full of life Species Diversity: 1000's of different species Trophic Levels: All 4 trophic levels Niches: Complex and lots Nutrient Recycling: Extensive, Complex
