A new, Ted-like event happening on Earth Day April 22, To learn more about this topic, as well as several other sustainability themed subjects, register here! In person seats are full, so please select the livestream option on the page and access instructions will be sent to you via email. Perhaps it sparks images of birds that fly south for the winter, or monarch butterflies making the journey across North America, or whales traversing the oceans of our planet. But what if I told you that trees are also capable of migration? While an individual tree is firmly rooted in the ground, as a species, trees can migrate over time. Such migration is in response to environmental challenges and climate change. This is especially pronounced in the Andean and Amazonian regions of South America. These are some of the most biologically rich ecosystems on earth. These landscapes also provide means of regulation for countless other global processes.Back to Publications Issues in Tropical Forest Landscapes Series This series of papers concentrates on critical issues faced in the rainforet and conservation of tropical forest regions today and has proved invaluable for delivering up-to-date, relevant information to research users on specific matters of concern.
The Centre worked closely with its research users in identifying these important issues. For each issue, the series examined the current state of scientific knowledge, research achievements, critical gaps in knowledge, priorites for action and management options. You can download issues from the series in PDF format directly below.
Original Research ARTICLE
They play important roles in the reproduction, regeneration and dispersal of plants within rainforests, eucalypt forests, woodlands and wetlands. During the day, flying foxes roost in communal camps, which provide them with a protected environment and a place to socialise continue reading safely rear their young.
In some cases, cities and towns have been built near the sites of traditional flying fox camps, while in other cases flying foxes have moved into urban areas and formed new camps. Within urban areas, flying fox camps can pose a nuisance keystone species in tropical rainforest nearby residents.
To help manage flying fox camps in urban areas, the factors that influence the location of camps were studied in southeast Queensland, the fastest growing urban area within Australia. This study found that most flying fox camps in southeast Queensland are located close to waterways in the coastal lowlands - the same zone that is intensively used for urban development.
Trees on the Run: Out of Breath & Out of Time
Even within this zone, flying foxes show a preference keystone species in tropical rainforest locating their camps within patches of suitable vegetation surrounded by urban areas, rather than in extensive forest.
Flying fox campsites occur in a range of vegetation types, but most comprise tall trees with a dense understorey, or are located in swamps or mangroves. At the local scale, there may be some potential for managing vegetation to alter its use by flying foxes, either to deter them from occupying certain areas or to provide new areas of suitable habitat. Rainforest cover has been removed from many landscapes with adverse consequences for biodiversity, climate, land condition and water quality.
Rapid, large-scale reforestation is required to restore biodiversity and ecosystem health in extensively and heavily cleared areas. While tree planting can re-establish a diverse rainforest on cleared land, the practice is expensive and only small areas of land have been reforested to date. Sometimes, forest cover can return to cleared land through natural processes.
Mesopredator Release Hypothesis
Most rainforest plants have fleshy fruits that are attractive to fruit-eating birds. As the birds move between remnant rainforest and regrowth patches they disperse the seeds of rainforest plants. These processes have the potential to cost-effectively restore forest cover to large areas of cleared land. In areas that have been cleared for long periods of time, regrowth may be dominated by introduced weedy plants. For example, regrowth dominated by camphor laurel trees covers extensive areas of cleared rainforest land in Keystone species in tropical rainforest. However, camphor laurel patches attract fruit-eating birds that disperse the seeds of rainforest plants.
Many seedlings of rainforest plants have recruited to camphor laurel patches and, in the long-term, may come to dominate the regrowth. This process could be hastened by careful and strategic management interventions, but this requires a change in current attitudes towards the role of weeds in ecosystem restoration.
Social diversity, racism and biodiversity
Back to top Issue 3, April Native Fish Stocking and Translocation Recreational fishing of rivers and dams in the Wet Tropics region of Queensland is a popular activity among locals and tourists alike. Thousands of people engage in recreational fishing each year, and demand is increasing as regional population and tourism industries continue to grow.
Fish stocking of popular recreational fisheries has been undertaken to cater for increased demand. However, zpecies research has shown keystone species in tropical rainforest, within the Wet Tropics alone, up to thirty-six native fish species have been stocked or translocated outside their natural range.]
