B. Thor Smestad (Canadian) B.S.F., M.Sc., P. Ag.
Thor Smestad is a Canadian reforestation and ecosystem-restoration specialist. He began this career in 1981 as a tree planter in the mountains of British Columbia (BC), Canada, and then later, after completing a degree in forest resources management (1994), continued to work in BC as a silvicultural forester. This work involved managing projects related to all aspects of reforestation and forest management on the vast expanses of public lands in British Columbia.
In 1997 he returned to university to complete a Master of Science degree, specializing in soils. His master’s study was located in western Kenya, where he examined the soil fertility changes associated with short-duration agroforestry fallows (Smestad et al., 2002).
Since completing his masters in 2002, Thor has worked throughout western Canada in the field of ecosystem restoration and soil erosion control. For a short period (2012 to 2016) he also operated his own native plant nursery and ecosystem restoration company. Many of the projects completed during this period were in shoreline and riverbank restoration, and he is now known as a specialist in this area in BC. One of the most exciting projects during this period was the ecological restoration of a small peninsula near Nelson, BC. Here, for a three-day period in each of five consecutive years (2011 to 2015), Thor co-led an annual ecological restoration field-school for the local College’s Integrated Environmental Planning Program.
At present he works seasonally (April-Nov.) as a senior ecosystem restoration specialist for an environmental consulting company in western Canada. He spends his winters in the Amazon region of Brazil where he is a founding member of ACRAA.

Katherin Daniela León Pinto
My name is Katherin Daniela León Pinto. I was born in Lara-Barquisimeto, Venezuela. I am 27 years old.
From a very young age I have felt a strong connection with plants. When I was 5 years old my family traveled to Valencia-Carabobo where my grandparents lived, they work mono-cultivation with citrus, milky and bananas. One day I asked my grandfather to teach me to work the land; that was my first contact, which led me to discover that this is my passion. Since then, a large part of my life has been dedicated to plants.
My family was a bit nomadic so we traveled a lot. We were in various states of Venezuela; we lived in cities, neighborhoods and towns. In each place I met people who shared their knowledge of plants with me, and this is something that I really liked. Every time I had the opportunity I read books about plants, and learned a little about natural medicine among other things.
Like the plants, I felt a great connection with the animals in each place where we arrived, and I rescued the animals that I found on the street and cured them. Most of them were cured with plants, so I practiced my home remedies. Those are my passions, plants and animals.
Of course life goes by and the world goes around and in those turns I lived and learned many things, and I am still living and learning. Now I live in Alter do Chão. Since I arrived here my work with plants has deepened, living two years in Caminho das Pedras, a small community near Alter do Chão that works with agroforestry. There I learned to work with multi-cultivation, agroforestry, and the biodiversity in the humid tropical zone; and with the soil here, which is sandy. This has been a great challenge with great learning.
I have been part of ACRRA for three years now; that is where I work, practicing and sharing everything I have learned. I am still seeking knowledge about plants, including at times taking courses on the internet about agroforestry. Daki is also a founding member of ACRAA.
