Kumbira Fieldwork 2015 – Trip 2

We did a second field trip to Kumbira from October 6^th to October 11^th. I (Aimy) and Ninda Baptista participated in this field trip together with Antonio Estrelinha (a freelancer photographer). We also were accompanied by Pedro Vaz Pinto (Giant Sable project), Nito Rocha and Wolfram Brock.

During this field trip we participated in a workshop organized by the local Administration of Conda. We had the opportunity to present the project in from of representative of the regional and local government, as well as the civil society (Figure 1). The objective of this workshop was to raise awareness regarding the need to establish a natural reserve in Kumbira.

We also met with Kumbira village school teachers to talk about the environmental education campaign we want to do with the students (Figure 2). The idea of this campaign is to build awareness about the forest importance and its biodiversity. We also had the opportunity to talk with the children and answer to some of the questions they had (Figure 3). During these meetings we had the company of Paula Reis. Paula was born and grew up in Kumbira and her family is owner of Fazenda Belita. She knows the people in the community and her participation in the environmental education activities will be vital to assure their success.

In the nursery, the plants have been growing well. We measured all the plants (Figure 4) and from the 141 saplings we planted in the first field trip, 133 have survived which represent a survival rate of 94%. However, we want to wait to our next field trip to see if this survival rate is maintained. Additionally, we planted 60 more saplings and expanded the nursery (Figure 5).

Kumbira Fieldwork 2015 – Trip 1

The first field trip of this year was marked by the beginning of our CLP funded project and took place from August 5^th to August 9^th. During this field trip we had a meeting with the administrator of Conda (the municipality where Kumbira is located), Mr. Fernando Fonseca, where we presented the project and share some ideas and concerns. Mr. Fonseca show himself very receptive and supportive with the project.

Then we continue our trip to Kumbira, where we met with the “soba” (traditional chief of Kumbira village). In this meeting we also presented the project and asked the soba for his permission to establish an experimental nursery within the community lands (Figure 1). The “soba” kindly indicated a suitable parcel of land that we could occupied for this task and the local people we could work with.

We set up the nursery with the help of two local workers, Arbino and Avelino. With the assiatnce of Michael Mills we collected saplings of native trees in the areas where old-growth forest was still present (Figure 2). Then, these saplings were planted in plastic bags and placed in the nursery that had a shade constructed by Avelino and Arbino using Inga vera branches and oil palm leaves (Figure 3).

THANK YOU CLP!!!

The Conservation Leadership Programme (CLP) has awarded our project with a Conservation Follow-Up Award. 

http://www.conservationleadershipprogramme.org/our-projects/latest-projects-2014/

This funding will allow us to perform conservation work on Kumbira: building awareness among local population and government, recover degraded areas and assess potential economic alternatives for the local community.

Thank you CLP!!!

Obrigado CLP!!!

Gracias CLP!!!

Kumbira Fieldwork 2014

In 2014 two field trips were done to Kumbira.

The first trip was carried out between May31^st to June 29^th, in which Hugo Pereira and Ana Leite participated, both of whom work at the Centro de Investigação em Biodiversidade e Recursos Genéticos (CIBIO). Hugo is a research assistant and Ana is a MSc student at CIBIO and is doing a thesis project entitled: “Can REED (Reducing Emissions from Deforestation and Forest Degradation) initiatives be used to conserve the unique Angolan Scarp forests?”

The second trip took place between August 2^nd and August 31^st, and I was joined by Henrique Costa and Ursula Franke. Henrique is a MSc student at the Science Faculty of the University of Porto and also happens to be my husband. Ursula is a German psychologist and bird ringer who had accompanied Michael Mills on other trips.

During these two field trips we did the following work:

Radio-tracking study for Gabela Akalat

A more extensive study was done to assess the home-range size and habitat preferences of Gabela Akalat. For this, mist netting was used to capture the birds, with the help of Michael Mills and Ursula Franke. To increase the species capture probability we used playback. Captured individuals were weighed, measured, tail feathers samples taken for DNA sexing and tagged using transmitters manufactured by Biotrack. Transmitters (PicoPip Ag 379) did not exceed 5% of the bird’s body weight and were attached with eyelash glue to the mantle feathers (Figure 1a & Figure 1b).

 Tagged birds were followed during five days with the help of Hugo Pereira (CIBIO, first trip) and Henrique Costa (University of Porto, second trip). Bearings for the birds were registered every hour (from 7:00h to 17:00h, with a recess at 13:00h) using a TR-100 telemetry receiver and a Yagi antenna, giving a total of 50 locations per each individual (Figure 2).

Figure 2. Henrique Costa following a tagged Gabela Akalat

Individuals were captured in four different sectors that were defined according to the forest characteristics as:

1. Invasive forest understorey and canopy is dominated by the invasive Inga vera, original from South America.

2. Natural best old-growth forest in the study area

3. Mixed forest with presence of a non-dominant Inga vera and other species

4. Coffee abandoned shaded-coffee plantations that are being transformed to agricultural plots.

A total of 16 Gabela Akalats were captured and radio-tracked. Only one bird's tag stopped functioning after 1.5 days of radio-tracking. I am not sure what happened with the tag, but as this tag was the one used in the experiments it is possible that there was some problem with the battery.

Bird point counts to register endemic species

Bird point counts were done in the “Alto Minho” area of Kumbira. The objective was to survey areas where no bird censuses were performed in 2010, 2012 and 2013. Bird point counts were done in the early morning, from sunrise (c. 6:15h) until the end of morning activity (c. 10:00h).  Point counts were done after playing a track of 30-second snippets of vocalizations of each of the threatened endemic species: Monteiro Bush-shrike, Pulitzer Longbill, Gabela Akalat and Gabela Bush-shrike. During five minutes after the playback all of the endemic species heard or seen in a 50m radius were registered, including Red-crested Turaco (Figure 3).

Figure 4. Aimy Cáceres doing a bird point count in the Alto Minho area

Repetitions were performed during the afternoon (c. 15:30 – 18:00h) only for the sample points that did not present any endemic. Sample points were separated at least 200m from each other in order to avoid double counting. A total of 83 bird point counts were performed. Gabela Akalat, Pulitzer Longbill and Red-crested Turaco were registered at some of the points. Even though Gabela Bush-shrike was not registered during point counts, Ursula captured one individual near the campsite confirming the presence of this species in the “Alto Minho” area.

Assess biomass capacity of Kumbira Forest

Ana Leite, with the help of Michael Mills, performed the vegetation surveys in selected sampling points. At each point a 10m x 10m plot was assessed for canopy cover using a densitometer and canopy height using a range finder. Tree height and diameter at breast height (DBH) for every tree with DBH> 5cm was measured within the plot. 54 plots were assessed and Ana will use this data to estimate carbon stocks from tree biomass for her master thesis project.

Other interesting things

Ursula spent some time teaching Sergio Fasz, a person from the local village, how to set nets capture and ring birds (Figure 6). Sergido is a person eager to learn and I hope he continues collaborating with us.

Visitors in the camp

Juliette Mills (Luanda International School), Nito Rocha and Rui Marcão joined us for the first days of the trip in June.

Kelse Alexandre, Anabela and Dennis (from the Angola Field Group) visited our campsite in mid-June (Figure 7). Kelse has been a great help with logistics in Luanda.

Presentation in Huambo

I was invited by the Instituto Superior das Ciências da Educação de Huambo (ISCED-Huambo) to give a presentation about the Mount Moco project (Figure 8). A group of teachers of ISCED-Huambo are interested in developing an education project in Mount Moco. We hope this initiative comes through as it will benefit the local population.
