Project Coordination Co-financed

www.embaixadadafloresta.blogspot.pt

we want to plant and care for 100,000 native trees by 2016

and we have in the metropolitan area territory in need of restoration

with native species of the Portuguese flora


Re-establish connections to our ancestors (Rute, Civil Engineer)

Favour Biodiversity (Manuel, Forest Engineer)

Reduce urban noise (Francisco, Student)

Sequester carbon dioxide from the atmosphere (Fedra, Designer)

Reduce the risk of fire spreading (Iva, Engineer)

Increase our well-being and personal productivity (Pedro, Manager)

Contribute to the formation of soil and protect it from erosion (Manuela, Biologist)

Stimulate our senses and decorate the “exteriors” (Ana, Journalist)

Infiltrate and filter water by increasing its quality (Artur, Environmental Engineer)

Have positive impacts on the health and welfare of children (Ana, Full-time mom)

we know that native trees are essential


Stimulate the senses, the minds and hearts of children (Joana, Manager)

Facilitate adaptation to climate change (Soraia, Environmental Engineer)

Promote psychological well-being and encourage physical activity (Luísa, Psychiatrist)

and so in the project FUTURE we

Plant trees and shrubs native to the areas

Care for our trees and areas with natural

regeneration

Monitor the state of our trees


Educate about forest and trees

in this geographical area


Municipalities: Arouca Gondomar Maia Matosinhos Oliveira de Azeméis Porto Póvoa de Varzim S. João da Madeira Santo Tirso Trofa Vale de Cambra Valongo Vila do Conde

our primary goal

Plant and care for 100,000 native trees by 2016


25,228 trees planted on 88.6 hectares = planting area equivalent to 90 soccer fields

3,914 volunteer participation = 38 citizens planting and caring for forests per week

11,598 volunteer hours = total of 16 volunteer hours per day

384 hours of activities held = 4 hours of volunteer work per week

75% survival rate = 7.5 in every 10 trees planted survive


and we have already achieved the following [2011-2013]

128 tons of CO2 per year1

= annually our trees capture the equivalent of 600g of CO2 per resident of the city of Porto3

€1,000,000 in ecological services per year2

= annually our trees ‘give back' to each citizen3 of the Porto Metropolitan Area €0.60 in ecological services

Note 1: Potential for carbon retention: annual average for a 40 year expectancy for the number of trees planted to date Note 2: Estimate based on the ability of the (adult) trees to capture CO2, atmospheric pollutants and intercept rainwater. Note 3: Total of 227,535 residents in the city of Porto and 1,663,277 residents in the Metropolitan Area of Porto (Census 2011)

overall results [2011 - 2013]


Year 1 = season 2011/12 Year 2 = season 2012/13
