About the Rainforest Alliance
Rainforest Alliance, a New York-based 501(c)3, and UTZ, an Amsterdam-based foundation, merged in 2018. Together, the new Rainforest Alliance is now a $70 million per year organization with offices in 17 countries (and growing) and over 5000 staff. The merged organization has two main offices—one in Amsterdam and one in New York City.
The Rainforest Alliance is creating a more sustainable world by using social and market forces to protect nature and improve the lives of farmers and forest communities.
We work towards making responsible business the new normal through our certification program, tailored supply chain services, landscape and community work and advocacy.
Overview and objectives
Rainforest Alliance is working with communities in the Mintom areas of southern Cameroon on Integrated Community Forest Management Programmes (ICFP). The objective of the programme is to strengthen community rights over forest resources to prevent forest conversion linked to agriculture, and forest-dependent communities generate higher incomes as economic incentives for forest conservation and restoration.
As part of the programme, Rainforest Alliance in collaboration with the High Conservation Value Network, is developing and piloting a simple and participatory methodology for communities to collect data to measure and monitor forest carbon stock and forest biodiversity. The methodology will support communities in updating their Forest Management plans, and to monitor carbon and biodiversity outcomes of the Forest Management plans. In developing the methodology, a consultant is being sought to conduct field data collection, which will be used to analyze and calibrate the simple forest measures of above ground carbon stock from detailed forested inventories.
Field data collection methodology
Data collection will be in four survey units, composed of three community forests and in an area of the Dja Fauna reserve. Each survey unit is approximately 5,000 hectares in size. Within each survey unit, data will be collected from a target of 25 sample points, with these sample points being randomly distributed within each survey area. A target of 100 sample points will be surveyed in total.
The consultant will be provided with the GPS location points for the sample points. Once in the field, some sample points may need to be repositioned, to account for in-field conditions such as areas that highly inaccessible. The objective is to minimise recorder bias in where sample points are located, to ensure the sample points capture the range of forest conditions.
Sample point data collection
At each sample point the following data will be recorded in the order outlined below, with field data sheets provided by Rainforest Alliance:
- From the centre point
- The exact GPS location of the centre point
- North, South, East and West photos
- Separate 360 degree visual sweeps that:
- Count all trees greater than a fixed object which is held by the surveyor at a fixed distance, e.g. arms length or by a string. See the angle count sample section of this reference. The Stand Basal Area is calculated from the tree count, size of the fixed object and fixed distance. Therefore the object distance and size of the fixed object must be recorded. After initial training and checking between surveyors on consistency, conducting a sweep count takes around 5-10 minutes.
- Count the number of trees in the following dbh size categories: 5-10cm dbh, 11-20 cm dbh, 21-30 cm dbh, 31-40 cm dbh, and >40cm dbh. Each tree does not have to be measured individually once the surveyor is confident in estimating the tree dbh without measuring the tree. Surveyor checking should be done early on, to double check surveyors are confident in estimating tree size class without actual measurements
- Records the presence (yes answers) of features from a provided set of questions (there will be max 10 questions, each are simple to answer quickly).
d. Across a 30m radius plot:
- Repeat step 3:i and 3:ii but recorded across the 30m radius plot
e. Forest Inventory data to calculate the above ground carbon stock
- In a 5.64m radius subplot measure the dbh of all trees that are 5-14.9 cm dbh, and where possible record its taxonomy to the lowest possible level, unknowns are recorded as unknown
- In the 12.61m radius plot measure the dbh of measure all trees with a dbh of >15cm, with where possible record its taxonomy to the lowest possible level.
Deliverable 1: An excel spreadsheet format (excel template to be provided) including field data, and accompanying photographs
