IPBio received a grant from Wildlife Acoustics whereby they donated 2 bioacoustics recorders and software to analyse the data. IPBio is attempting to understand peak activity times for different species throughout the 24 hours in a day. This study will be conducted over the years to develop monthly/seasonal peak activity period for species. In addition, IPBio wishes to create a “sound bank” of all the species on the reserve. – The volunteer is responsible for hiking to the site to set up, change memory card and return the Song Meter 4 hardware. – The volunteer will collect the data from the memory card and filter the audio recordings. – The volunteer will use the Song Scope software to analyse the data and save sections of recording into the audio recogniser.

Free Time Activities

Caves: Iporanga is called “The Cave Capital of Brazil” with over 400 caves in the town. Below are just the highlights.

  • Casa da Pedra is the world’s largest cave entrance of 215 meters. The trip involves a 2-hour hike to the opening where there is a place to sit down and have a picnic and swim and then a hike back.
  • Temimina Cave has a large opening in the ceiling illuminating its oddly shaped diagonal garden. Then you enter into a dark cave where at the end you find a natural shower hole.
  • Nucleo Santana is a group of caves and is the most commonly visited as it has a wide range of different types of caves. In some caves you can swim.
  • Tubing/Boia Cross: is a sport where by you get on a big balloon and float down the river. There are various waterways you can do in Iporanga, some more radical and some in the big river which is very relaxing and can last 3 hours.
  • Cananeia: has various islands with dolphins swimming in between which are very easy to visualize. It is also known for its stunning beaches, awesome boat tours, great restaurants and the mangrove reserve where there are many crabs.
  • Waterfalls: Iporanga has many waterfalls. “Sem Fim” is a small waterfall walking distance from the reserve. “Vale das Ostras” has 12 large waterfalls in a row. - Quilombos: during the era of slavery many slaves would run away from the plantations and create settlements hidden in the forest. These communities live in relative isolation and you can visit their small towns. For some of the Quilombos the tours include travelling their by boat and having a traditional lunch at one of the families homes.

Social Events:

  • Dinners: there are many nice restaurants were volunteers can have dinner, some more classy like Casarao and some with traditional Brazilian food. There is also a great fish restaurant. Often volunteer will eat out on the weekends.
  • Town Parties: the are a couple of bars in town, some have pool tables and some have dancing areas. On holidays, there are usually town festivals on the streets.
  • BBQ: it is very common to have a BBQ on the weekend which is often accompanied with the traditional Brazilian drink called Caipirinha.

Pricing Breakdown

Volunteers at IPBio are required to pay 650 reais per week (please check up-to-date exchange rate in your currency). This fee covers the volunteer’s accommodation, internet access and project costs for the specific dates agreed upon. Volunteers are also responsible for paying for any extra costs such as travel costs, visa costs etc. A volunteer only confirms their placement once their payment is made. Once a volunteer makes their payment there is no refund if they decide to cancel for whatever reason. We will provide you with specific payment options by email.

The currency in Brazil is the Real. There is an ATM machine in Iporanga which accepts Visa Credit/Debit cards. ATMs give a better exchange rate than Exchange Houses. Check with your bank to see if your cards will work in Brazil, and tell your credit card company that you will be traveling overseas. Exchange some money prior to arriving in Brazil. The amount of money you want to bring is really up to you. Volunteers are responsible for purchasing products for the house such as garbage bags, cleaning products and toilet supplies. Volunteers are also responsible for buying their own food and cooking for themselves. On average a volunteer spends 450-1000 reais a month on total although of course this varies on your lifestyle choices. This covers living costs such as food, drinks, transportation and house supplies. On the high end of 1000 reais you would be going out for dinner regularly and doing various weekend activities but this is up to each volunteer hence we put a price range. Dinner out (without drinks) ranges from 15 to 30 reais. Cost of tours (including a guide, equipment and entrance fee costs around 110 to 140 reais depending on how many volunteers go.

Not Included in Price

Volunteers are also responsible for paying for any extra costs such as living costs, travel costs, visa costs etc.
