Identifying and implementing alternative, income-generating elephant unpalatable crops as soft barriers to subsistence crops

A lot of is still unknown about elephants’ dietary preferences and deterrence crops. To expand our knowledge and create replicable methodologies, we studied elephants’ preferences towards 18 different types of crops, the majority of which are of high combined economic value (food, essential oil, medicinal and bee fodder value) and suitable for growing in Southern African climates. The cafeteria-style experiments allowed us to evaluate several plants that have never been tested in terms of their palatability to elephants. Our results showed that herbs such as borage and rosemary with medicinal and aromatic properties, respectively, were strongly avoided together with bird’s eye chilli (a well-known elephant deterrent crop). We found that lemon grass and sunflowers, presented as whole fresh plants to the elephants, were edible to the elephants. This is surprising, as both plant types have been described as unpalatable to both Asian and African elephants alike.

According to our overall scoring system, four food types proved best suited for the proposed corridor region (Bird’s Eye Chilli, Cape Gold, Cape Snowbush and Rosemary). Of these, only Bird’s Eye Chilli had been tested before. The other three plant types have been used in producing essential oil and hold great promise for income-generation.

  • Approval by relevant animal ethics committees
  • Access to (semi-)habituated, and human-friendly elephants
  • Access to fresh forms of plant crops to be tested
  • Experiments to be carried out by qualified researchers, according to scientifically correct framework & methodology, subject to peer-review before publication
  • Supporting staff and research network

The semi-habituated elephants are intelligent and could easily become bored with the experimental setup. It did help that the set out of the food type sequence was randomised every day. We also learnt that the time of experimentation did have a role to play, thus in the afternoon the elephants seemed more hungry and agreeable to approach and test every experimental food bucket. Filming the entire experiment help with the analyses as data recording on site could become complicated depending on the elephant’s behaviour and the ability to replay the sequence of event was helpful.

Mapping wildlife corridors linking Protected Areas using satellite tracking of elephants

Starting from the knowledge that over 50% of elephant movements are outside of Protected Areas (PAs) and over 75% of elephant populations are transboundary, we used a satellite tracking approach to identify which wildlife corridors are most used by elephants.

 

While our initial plan was to establish a corridor between Gonarezhou (high elephant density) in Zimbabwe with Banhine and/or Zinave National Parks (low elephant density) in Mozambique, insufficient tracking data and reports linking the PAs in these countries (Zimbabwe to Mozambique) to define a conclusive corridor has made us shift our geographical location to Namaacha Valley in southern Mozambique. Here several elephants that we had collared outside of PAs in the hope to find more corridor moving individuals between PAs across southern Mozambique, have defined a vital corridor covering the southern extreme of the KNP, south towards Tembe National Park in South Africa and east towards the Futi corridor and MSR on the coast of Mozambique.

 

The collaring of elephants and analysis of the tracking data have shown us that existing PAs are too small for elephants. Using elephants as the landscape planners for connectivity across national boundaries, enabled us to identify human-elephant conflict hotspots where efforts are most likely to have the largest impact.

  • Sufficient funds to purchase collars and pay for helicopter fees are critical to the success of this part of the strategic plan.
  • Helicopter & pilot availability can be challenging in remote areas.
  • Cooperation from the community on where and when elephants are in the corridor regions.
  • When working in a large Transfrontier Conservation Area, logistical support from partner organisations is key for successful longterm implementation.

We have learnt that corridor moving elephants are wily and are thus not often seen during the day when they can be collared. They have hideouts during the day to avoid conflict with people. We have managed to find suitable study animals by collaring one or more bulls within a group of bachelor bulls close to the border of protected areas or even within protected areas. This has helped us find additional animals when the groups split up over time. Also having a mobile Rapid Response Unit informing us of elephant movements, has helped us supply collars when needed to the Mozambique Wildlife Alliance who can deploy them quickly and efficiently on the ground. Writing ahead of time for funds via grants, has also enabled us to have funds. Expensive helicopter flying time and availability of pilots has remained a challenge.

Crear condiciones habilitantes para la intervención del Mecanismo TDC en las comunidades socias de la Reserva Comunal Yánesha (1)

La cogestión de la RCY en colaboración con la Asociación Nacional de ECA del Perú (ANECAP) apoyaron a las comunidades a lograr las condiciones que les habilitaron para acceder al Mecanismo TDC. Por ejemplo, se elaboraron siete planes de vida y se actualizaron documentos legales y administrativos.

  • Disponibilidad de la cogestión SERNANP-ECA AMARCY para configurar e implementar el modelo de articulación
  • Apoyo financiero y técnico de ANECAP y la ONG Desarrollo Rural Sustentable-DRIS para completar las condiciones normativas y metodológicas del mecanismo
  • La experiencia de la cogestión de la RCY en la gestión de proyectos que implementa como parte de los Lineamientos de sostenibilidad financiera de las Reservas Comunales del Perú, hizo posible que se canalicen fondos para la implementación de las condiciones para acceder al mecanismo TDC
  • Se fortaleció el modelo de cogestión entre el SERNANP-ECA AMARCY. Para el establecimiento de los compromisos del acuerdo tripartito se revisaron las funciones del ECA AMARCY para la gestión de la RCY y con el mecanismo de TDC se planteó implementar acciones de conservación y aprovechamiento sostenible en los territorios titulados de las comunidades, que se encuentran fuera de la RCY, en su Zona de Amortiguamiento y paisaje asociado.
  • Se incrementó el número de comunidades nativas miembros del ECA AMARCY, que se convirtieron en beneficiarias del Mecanismo TDC. Antes de la implementación del acuerdo tripartito, sólo dos comunidades habían aceptado el ingreso del mecanismo, y con la preparación y mediación de la cogestión, en total 9 comunidades nativas Yánesha llegaron a firmar el convenio con el PNCBMCC para acceder al mecanismo TDC.
