Aquatic insects, particularly members of the Order Odonata, have been long considered as good bioindicators for tracking response in ecosystem shifts and gradients, in both larval and adult life-staged (Valente-Neto, et al., 2016). In tropical regions, Odonata diversity can be high. The forests and peatlands of Kalimantan (Indonesian Borneo) are one area that accommodates a variety of Odonata species with high endemicity due to habitat diversification (Dolný et al., 2011; Dow & Silvius, 2014). One ecosystem that has not been explored extensively for its Odonata communities is the mixed-mosaic heath (kerangas) forests. Three previous studies on Odonata have been conducted in only heath forests in Indonesia (Orr, 2001; Orr, 2006; Purwanto et al., 2019). With this in mind, we conducted a preliminary study of the Odonata community in the mixed mosaic kerangas dominated forest of the Mungku Baru Education Forest (KHDTK) in Central Kalimantan, Indonesia.
This research was led by Jorian A. Hendriks as part of his undergraduate thesis at the Maastricht University, Netherlands. The research contributes to a larger programme of documenting the biodiversity of and conserving this unique habitat type in Central Kalimantan undertaken by Borneo Nature Foundation (BNF) and Universitas Muhammadiyah Palangkaraya (UMP) who manage the KHDTK along with the local community of Mungku Baru. This research was conducted for a period of three months from November 2019 to February 2020. Data mobilization and publishing were supervised by BNF and the Faculty of Forestry, Universitas Gadjah Mada, through the Biodiversity Information Fund for Asia (BIFA). All activities were conducted under required permits from relevant local and national institutions in Indonesia.
Purpose
As a part of the Sundaland Biodiversity Hotspot, Borneo is incredibly rich in biodiversity. Despite this, scientific knowledge of species distribution and habitat requirements across the island of Kalimantan remains extremely limited, owing to limited historical scientific attention and low accessibility of much of the data that does not exist, which frequently remains unpublished or buried in grey literature. This is reflected in peer-reviewed journals and the low number of records for the region in the GBIF database. Such low geographic and taxonomic biological data availability over such a large, biodiverse, variable area as Kalimantan hinders effective conservation planning at both site and landscape levels. Our goal in using and publishing resources on the GBIF database is to help enhance biodiversity research and conservation efforts in Kalimantan through increasing data availability for research analyses and to inform support evidence-based conservation policy decision making.Sampling Description
Study Extent
The research was conducted in the the Forest Area for Special Purposes (KHDTK), Mungku Baru that covers 4,910 ha of a heath dominated mixed mosaic habitat type that is characteristic of the larger landscape that it is situated in. In this research, data collection was conducted in an existing transect system, where two transects were chosen in each of the three main distinguishable habitat types within the mosaic, i.e. Kerangas (K), Low pole peat forest (LP) and mixed swamp forest/stream edge forest (MSF).Sampling
Two lines transects of 250 m in length and 0.5 m in width were surveyed for Odonata within each of the three habitat types (Kerangas, low pole peat and mixed swamp forest), resulting in six transects in total. Each transect was surveyed twice per day at 09:00 and 14:30 Western Indonesian Time, to coincide with the peak activity period of Odonata. To better represent habitat conditions and their impact on Odonata ecology, the transects included both water and open canopy areas for each habitat category. Throughout the study period, each transect was surveyed eight times. All Odonata spotted during surveys were captured using an aerial net. Each individual captured was marked (abdomen or wing with a permanent marker), photographed, and released at the site of capture. To ensure accurate identification, photographs were taken of the lateral, dorsal and ventral views, and close-ups taken of their anal appendage. The surveys were only conducted on clear days without rain. Any behaviours/activities such as feeding, mating, ovipositing, and tenerals were recorded as additional data. In such cases, individuals were not captured using nets but were still identified by sight to the species level when possible.Quality Control
1. Surveys were conducted based on best practice field guidelines for flying insect surveys (Pollard, 1975; Pollard, 1977; Walpole & Sheldon, 1999; Van Swaay, 2003; Oppel, 2006). 2. All data were collected using a standardised method (line transects with Odonata captured using aerial nets and released). Transects were fixed at 250 m in length and 0.5 m in width. Survey times and days were kept constant over the study period. 3. Specific field data sheets were prepared accommodating all relevant data for Odonata surveys, including species identification and recapture remarks, habitat type, environmental data, weather data, morphological measurements and demographics of each caught individual. 4. Data were recorded by trained personnel to minimise risk of death or damage to individuals during capture and to ensure consistency in data collection and quality. 5. The main field guide used for Odonata identification was developed for the nearby Sebangau National Park by B. Holly, I. Kulu and Iwan (2018) and 'A Guide to The Dragonflies of Borneo' by Orr and Hämäläinen (2003). Additional literature sources and researchers with past experience of surveying Odonata in the region (B. Holly, R. Dow) were consulted for assistance in identifying unknown species. Online biodiversity databases were also used in some cases (e.g. biodiversitylibrary.org). 6. Field data were inspected, cleaned and any taxonomical issue with respect to nomenclature were resolved. The data were transformed to the Darwin Core, ISO, UTF-8, and JSON standards and formats. To ensure the quality of the data, it was double checked by relevant project personnel.Method steps
- Odonata were surveyed through walking transects of 250 m length using the aerial nets method to capture, identify, mark and release sighted individuals.
- Surveys were conducted twice a day at 09:00h and 14:30h, during the peak activity periods of Odonata
- Each adult Odonata sighted during surveys was captured, photographed, identified, marked and released at the site of capture.
- Weather data (categorized into sunny, cloudy, windy, rainy, and rain-laden clouds) was visually determined every 15 minutes. Surveys were not conducted during rain.
- Environmental data on the percentage of surface water, pH and temperature of surface water if present, surface water attribute (lotic, lentic or absent), incident light (direct or diffused) and canopy cover were recorded at each capture location within a 5 m diameter of the sight of capture and at every 25 m intervals on the transect.
- Unknown species were identified with the assistance of regional Odonata experts and identification reference guides.
- Data from tally sheets were digitized into Excel worksheet format and stored in a single electronic database. From the original dataset, data were cleaned and only relevant fields for this occurrence resource were retained.
- All scientific names and taxonomic validations were redone by the resource creator using GBIF backbone and Global Name Resolver to ensure the species names were accurate.
- Field notes form the original data were separated into four different remarks as per the Darwin Core Standard i.e., organismRemarks, identificationRemarks, occurrenceRemarks and eventRemarks .
- Measurement data were segregated and included in the DwC field dynamicProperties and taxonRemarks fields. The dynamicProperties contain environmental data such as percentage of surface water, pH, and temperature, whereas the taxonRemarks field includes morphological measurements of individual Odonata captured during surveys.
- All data in this dataset were standardized to ISO 8601, ISO 316-1-alpha-2, JSON, and Darwin Core standards.
- Data cleaning, transformation, and formatting involved using Microsoft Excel and Open Refine.
- Final steps for preparing this dataset were done by running it through the GBIF validator.
