Classification Format

The Regeneration Trail is about a one kilometer walk through twenty years of rainforest regeneration. The farther one walks on the trail, the older the planted vegetation. Aside from slight variation due to cyclones, the rainforest gets taller and denser as one progresses. Trees identified on the regeneration walk are labeled "Regeneration Trail".

The Dubuji Boardwalk is a one kilometer track through rainforest, mangrove forest and swamp. Because the boardwalk winds through natural, untouched rainforest, there are old plant species that can't be seen on the Reforestation Trail. Plants identified on the Dubuji Boardwalk path are labeled "Dubuji Boardwalk".

Titles of plant entries include species name and common name.
Tags on plant entries include species name, synonyms of species name, and more widely used (yet sometimes incorrect) species names.
Plants are labeled "Pioneer species", "Primary successional", and "Secondary Successional" when appropriate

Regeneration Trail Data

Three other students (Cory Baker, Tanya Bitcon, Elizabeth Eck) and I collected data about the regeneration process. Every 20 meters, in a straight line through the land Dr. Spencer reforested, we randomly selected a 4x4 meter plot, staked it out for measuring, and recorded information about the trees in each. We did this for 16 plots, extending approximately one kilometer from the first plot in 1992 to the most current plot of 2011. Although it is not exact, each plot represents about one year of growth. Each year, Dr. Spencer planted new vegetation roughly every 20 meters. Plot #1 is the first plot planted in 1992; Plot #16 is the last (most recent) plot planted in 2011.

We focused on total number of trees, number of saplings/seedlings (young trees under 2 cm), and the circumference of each tree (categorized into three groups: Under 5 cm, Under 20 cm, and Under 100 cm). This gave us an estimate of the total growth of the area. The following is a summary of our findings. In the graphs and photo series it is easy to notice the gradual decline of vegetation, aside from a few outlier plots primarily due to cyclone damage. Graphs are courtesy of Tanya Bitcon. The x-axis is the number of meters along the regeneration trail, with 0 meters marking the beginning of the trail (vegetation planted in 1992) and 300 marking the end of the trail (vegetation planted in 2011). Pictures of each plot are courtesy of Tanya Bitcon and Elizabeth Eck.

Cluster Fig (Ficus racemosa)

http://keys.trin.org.au:8080/key-server/data/0e0f0504-0103-430d-8004-060d07080d04/media/Html/taxon/Ficus_racemosa.htm

Ficus racemosa
Common Names: Fig, Cluster; Cluster Tree; Figwood; Fig Tree; Cluster Fig

The cluster fig is often found near river courses and drainage lines. It can become enormous. Many birds and animals rely on the cluster fig for food. The fig has male and female trees --- male trees produce figs on the trunks that are home to wasps; the female trees have the seeds and are pollenated by the wasps that come from the male trees. This is one of the few specializations that has developed in the tropical rainforest of Queensland. The cluster fig is a secondary successional tree.
