PPBio International

The Center for Innovative Conservation Strategies (CICS), realizing the necessity for cost-efficient biodiversity surveys that can be used for long-term ecological studies has been investigating biodiversity survey methods since its inception and has found that, although some of the current systems are adequate for some taxa, or particular questions, most are not adequate for the needs of most users (conservation planning, environmental impact assessment, bioprospecting, monitoring of harvesting, among others).
 
This conclusion is supported by recent studies by University of Queensland Researchers (Lawson et al. 20051). The only system currently available that can provide the information required by the majority of stakeholders is that of the PPBio. 
 
 
For this reason, the Center is developing PPBio – Australasia: a consortia of universities, councils, federal agencies and landholders to implement PPBio grids in eastern Australia. The need for an efficient system is felt by most managers, and initial meetings in 2005 attracted over 50 land managers from local, state and federal agencies as well as individual landholders. 
 

PPBio Australasia is led by Professor Jean-Marc Hero and is based out of the Environmental Futures Research Institute, Griffith University, Gold Coast.

There are three PPBio grids and one set of modules installed in Australia (Figure 1). There is one set of modules installed at Chitwan National Park, Nepal. The details of the grid and modules can be seen in Table 1.

Karawatha Forest Park

Karawatha Forest Park (27°38’00”S, 134°04’56”E) is a 909 ha peri-urban forest governed by the Brisbane Shire Council. The first established Australasian PPBio site was initiated in collaboration with Brisbane Shire Council, South-east Queensland Catchments and the Nature Refuge Landholders Association in 1997. Vegetation types and structure within Karawatha Forest Park (KFP) have been influenced by past management practices. The local region was logged from the 1850s to the late 1950s for firewood, housing material and coal production. Urbanisation and housing encroachment through partial clearing reached the area in the early 1980s. Many parts of Karawatha are burned every one or two years, mainly by low intensity fires. KFP is currently used for bushwalking, picnicking, mountain biking and nature research. The vegetation is characterised by remnant mixed eucalypt forest with a predominately grassy understorey and melaleuca forest with a fern and herbaceous understorey.

 

Unlike other Australasian PPBio sites, transects were placed 500 m apart to ensure adequate replication. Scientific studies have shown that this spacing is adequate for independence of data. Most scientific research conducted at KFP has been undertaken by Honours students. So far, ten Honours studies have used the KFP PPBio grid for scientific research. Completed theses are listed in Table 2.

The PPBio grid at KFP is also became part of a Terrestrial Ecosystem Research Network (TERN) SuperSite in 2010. The Australian SuperSite Network (ASN) is a national network of multidisciplinary ecosystem observatories. The ASN includes ten SuperSites that each represent a significant Australian biome. The network covers all States and Territories and spans a wide range of environmental conditions.

Lake Broadwater

Lake Broadwater (27°12’35”S, 151°06’45”E) is a Conservation Park and Resources Reserve that is run by the Queensland Department of National Parks, Sporting and Racing. The centrepiece of the park is a naturally-occurring shallow freshwater lake that is lined by Eucalyptus tereticornis. Vegetation is predominantly Eucalyptus woodland with a grassy understorey. Land clearing for the sake of grazing has occurred historically, before the land was gazetted as an Environmental Park in 1981 and a Conservation Park in 1994. Much of the Park and Reserve is regrowth and woody vegetation can be patchy as the distance from the lake increases. The surrounding area is used for cropping, grazing and gas extraction.

 

Eighteen PPBio transects have been installed over 2007-2009. The transects have been visited yearly since 2007 to conduct undergraduate research with mammal, bird, weed, reptile and amphibian data collected yearly.

Currawinya

There are 40 PPBio transects at Currawinya National Park, Queensland (28°50’23”S, 144°29’34”E). Currawinya contains a 2487 ha enclosure for the purpose of breeding the nationally Threatened greater bilby (Macrotis lagotis). During 2010-2012, thirty transects were installed inside the enclosure and 10 transects were installed outside the enclosure. The environment within and surrounding the enclosure is semi-arid with the predominant vegetation being shrubland comprising of Eremophila and Dodonaea species. Low red sand dunefields occur at the topographic high points, while water runs into claypans.

 

Monitoring of bilbies and rabbits has occurred since 2011 and research on the PPBio transects has documented their decline due to a cat invasion. Mammal activity, including goat and kangaroo activity has been monitored on transects outside the enclosure. There are marked differences in vegetation condition and cover either side of the enclosure fence due to pest herbivores.

Cooloola

Two modules, consisting of one and three PPBio transects each, have been installed at the Great Sandy National Park (26°15’37”S, 153°03’24”E) in southern Queensland. The modules are 5 km apart, with transects being 1 km apart within a module (Figure 5). As is the case with Lake Broadwater and Currawinya, the national park is run by the Queensland Department of National Parks, Sporting and Racing. Habitat is wallum heath on a sand dune system. A study on groundwater movement has been undertaken on the modules.

Chitwan National Park

Sixteen PPbio transects have been installed at Chitwan National Park (27°32’47”N, 84°29’42”E) in lowland Nepal over a period from 2007 to 2011. There are five transects in riverine forest, one in grassland and ten transects in Sal forest (Figure 6). A complex collaboration with World Wildlife Fund Nepal, the National Trust for Nature Conservation (NTNC), the Department of National Parks and Wildlife Conservation (DNPWC), the Center for Molecular Dynamics and Tribhuvan University has resulted in seven student research trips conducted by staff and students from Australia and Nepal. The PPBio Nepal program focuses on research development and education for Australian students and Nepalese staff and students. Since 2007, monitoring of woody vegetation, small and large mammals, birds, weeds and DNA sampling has taken place. The goal of the PPBio Nepal is to hand over management of the PPBio grid to Nepal.
