12 Comiskey and Dallmeier 5 Adaptive Management in Takamanda Much more baseline information needs to be collected from TFR, but as knowledge of the different taxonomic groups increases, conservation and management recommendations will be developed and adjusted. Design and implementation of conservation efforts that sustain biodiversity at an optimal level are a key goal for stakeholders in the region. Thus, the effectiveness of conservation and management decisions must be closely monitored in the future. There is no land-use or management plan for TFR. Such a plan will comprise the first step to protect and manage the reserve. The plan should describe the resources that are of importance to the area and strategies for their conservation, leading to a monitoring program to ensure the most effective management. 5.1 Monitoring Objectives and Planning Monitoring within the adaptive management framework involves the collection and analysis of repeated measurements to evaluate progress toward meeting conservation management objectives (Comiskey et al. 2000). The initial steps in defining and establishing the monitoring program involve the collection of baseline information that helps to establish conservation priorities, a process that has been initiated in TFR. Changes in biodiversity have many causes, including (among others) variations in natural population cycles, climatic effects, and direct impacts from human activities, and these are not fully known for the Reserve. Some monitoring activities are already in place at TFR; ten one-hectare biodiversity plots have been established along an altitudinal gradient to evaluate long-term changes in floristic communities (Sunderland et al. this volume); monitoring of large mammals and apes—key indicators of general ecosystem health and human activities—is in place (Sunderland-Groves et al. this volume); and changes in land use have been monitored using remote sensing over a ten-year interval (Slayback this volume). The other assessments described in this volume will provide the baseline upon which priority Takamanda: the Biodiversity of an African Rainforest taxa can be defined for monitoring and against which future change can be evaluated. 5.1.1 Stakeholder consultation Further stakeholder participation will help to identify the next steps and priorities based on current knowledge of TFR. Through continued stakeholder workshops and consultations, critical biodiversity issues can be identified, including priority areas for further assessments, indicator species or taxa for monitoring based on current knowledge, potential conservation and management strategies, and resources needed for the next steps. For example, it is known that the population of apes in the region is unique and threatened (Sunderland-Groves et al. this volume) and may be flagship species for conservation. Likewise, several important bird species may serve as indicators for monitoring and conservation purposes (Languy and Motombe this volume). 5.1.2 Identify resource needs An understanding of resource needs is essential to ensure success of the project. Critical resources include time commitment and funding allocated to the project, as well as a sufficient number of trained people to conduct biodiversity assessments, devise monitoring strategies, and improve sampling protocols. These elements must be balanced with professional expertise, adequate technology to manage information and voucher collections, and an appropriate budget for field equipment, data management, and publications. For TFR, resources are a particular challenge because of the remoteness of the region and the difficulty in accessing sites where assessment and monitoring must be conducted. 5.1.3 Capacity building Continued support for local capacity is definitely needed for the long-term success of monitoring projects. Support and training should focus on developing the capacity of ecologists who are already familiar with the ecosystem types in the Reserve, taxa-specific specialists, skilled
Adaptive management Monitoring Objectives and Planning field technicians who can gather and identify field samples, data managers, and geographic information system (GIS) specialists to compile the information. SI/MAB has found it useful to conduct courses in which participants with an interest in continued training are identified and supported through on-the-ground training during biodiversity assessments. Such candidates can reach a high level of expertise through hands-on experience, and, in some cases, this has facilitated their continued academic and professional careers. Through SI/MAB’s vegetation assessments at TFR, three Cameroonian collaborators have furthered their education by completing Masters-level studies at local institutions.

Assessment and Monitoring 5.1.4 Defining specific management objectives and responses Once conservation priorities and the potential indicators or species of conservation interest are identified through consultations, the next step is to design a management strategy. For the TFR, the ideal management plan should include clear and specific objectives related to biodiversity—for example, maintaining the population of Cross River Gorillas at current levels. Such objectives provide the base for launching the monitoring program, which should be targeted at meeting the objectives. A “threshold” level should also be determined, beyond which some form of intervention would be required to ensure the long-term survival of the population(s) being monitored. In the case of the Cross River Gorilla, a threshold population density must be 13 SI/MAB Series #8, 2003
