1. Background of consultancy assignment
Flooded and seasonally inundated forests in eastern Thailand are ecologically important ecosystems that provide essential services such as flood regulation, water purification, carbon storage, and habitat for diverse plant and animal species. These forests occur primarily along rivers, wetlands, and floodplains, where periodic flooding strongly influences forest structure and species composition.
Despite their importance, flooded forests in eastern Thailand remain poorly studied, particularly in terms of tree species diversity and distribution. Most existing forest surveys focus on upland forest types, resulting in a lack of baseline data for riparian and flooded forest habitats. This information gap limits effective conservation planning, forest management, and restoration efforts, especially as these ecosystems face increasing pressure from land-use change, hydrological alteration, and climate variability.
A tree species survey is therefore necessary to establish baseline ecological data, support informed management and restoration planning, and improve understanding of these under-studied forest ecosystems.Top of FormBottom of Form
2. Objective of the consultancy
The purpose of this agreement is to engage the Service Provider to conduct a tree species identification survey in flooded and riparian forest habitats in Eastern Thailand. The survey will contribute to improved ecological understanding, conservation planning, and future restoration efforts.
3. Scope of work/ Major responsibility
The service provider will:
3.1 Produce a tree species list for flooded and riparian forest. A complete species list of vascular plants (gymnosperms, ferns, monocotyledons, and dicotyledons) found in the area.
3.2 Write and submit a report with all info described above with separate tables for tree species, and vascular plants. Each table should include at least the following information: local name, botanical name, habit, ecology, and conservation status.
| No | Activity | Expected output | Timeframe |
| 1 | Forest survey | The service provider will identify and record all species selected during field survey | 9-13 Feb 2026 |
| 2 | Write and submit the agreed report | The service provider will write a report with all agreed information and submit by the agreed due date | 13 Mar 2026 |
5. Required profile:
Knowledge/Expertise:
- Expertise in tropical plant taxonomy and tree species identification
- Proven field experience in lowland, riparian, and seasonally flooded forests
- Familiarity with regional floras, identification keys, and herbarium references
- Ability to identify tree species using vegetative and reproductive traits
- Experience in collecting and documenting voucher specimens
- Capacity to record accurate field data, including GPS locations and habitat information
6. Experience:
· Proven experience (minimum 5–10 years) in botanical field surveys, with a strong focus on tree species identification
· Demonstrated experience conducting forest inventories or biodiversity surveys in tropical forest ecosystems
· Prior experience working in flooded forests, riparian forests, wetlands, or seasonally inundated habitats is highly desirable
· Strong practical experience in in-field identification of trees, including seedlings, saplings, and mature individuals
· Experience using regional floras, dichotomous keys, and taxonomic references relevant to Southeast Asia
· Proven ability to collect, prepare, and document herbarium specimens following standard scientific protocols
· Familiarity with local and scientific nomenclature, including synonymy and taxonomic updates
· Experience working with GPS, mapping tools, and standardized data collection forms for ecological surveys
· Ability to work in challenging field conditions, including flooded terrain, remote areas, and variable weather
· Previous collaboration with local communities, field assistants, or government agencies is an advantage
· Experience contributing to technical reports, species lists, or ecological assessments
· Knowledge of conservation-relevant species, including threatened, endemic, and protected tree species
· Experience complying with national regulations and ethical guidelines related to biological surveys and specimen collection
