Our approach to reforestation

Treeseve acts as a project manager to set up dense and diversified planting projects. Our offer is turnkey, from the search for the land to the organization of the plantation, up to the certification process. Companies finance all costs as part of their CSR policy (Corporate Social Responsibility) or their Climate strategy *.

5 essential aspects underpin our engagement

1.Scientific Approach

We audit, measure and collect data on our dense and diverse plantations, from the ordering process (nursery invoices) to local data collection tools (Smartphones and tablets allowing the field manager enter the data), supplemented by aerial photos by drone/satellite). Thus, every year for the first 5 years, then every 5 years, we measure the survival and growth rate of our trees, i.e. their CO2 capture efficiency, as well as the evolution of local biodiversity, both plant and animal. This data is shared with research laboratories such as the Crowther Lab at ETH Zurich (project Restor).

2. Prioritize the local ecosystem

3. Botanical Innovation

 

In the early 1970s, Prof. Miyawaki developed a planting method to recreate primary-type forests in Japan.

We use this low-tech method for its very high forest growth (i.e. carbon accumulation), improved land use efficiency and optimal biodiversity enhancement.

In addition, these dense and varied type forests provide ecosystem services referring to all the benefits that we derive from forests, directly or indirectly, to ensure human well-being: water, carbon storage and wood, plant and animal biodiversity, soil preservation and human recreation.

Treeseve has developed robust organizational know-how which has enabled it to go from 2,500 trees planted in December 2020 on a single site, to 36,000 trees planted in February-March 2021 on two consecutive sites.

 

1. Diversity

A wide variety of trees are planted: generally25 to 35 local species of trees and shrubs are chosen taking into account their ecological function. This diversity of species allows, through interactions between trees, better productivity (and therefore more efficient carbon storage), but also better resilience.

2. Density

Up to 30 times more plants are planted (3 plants per m2) than in a conventional forest plantation. High planting density intensifies the effect of tree interactions, increasing the positive effects of species diversity. The density will also favor the reconstitution of the humus, with the trees which by dying contribute to the enrichment of the soil.

3. Efficiency

After 3 years of monitoring in the growth period,the Miyawaki type forest is left to its natural development, to eventually form a well-tiered and impenetrable forest. In 30 years, we thus end up with the reconstitution of a young quasi-natural multi-layered forest

What we need is a new ecological approach, commensurate with our times

4. External Audit Process

 
We are part of a certification process for the valuation of quantitative and qualitative elements. Labelling by an independent third party is a key step since it certifies that our projects comply with precise specifications in terms of planting method and origin of the plants. It also makes it possible to quantify the efficiency of our dense and diversified plantations in terms of carbon capture and the creation of biodiversity.

Treeseve has obtained the following Certifications:

  • July 2021 – Biodiversity for All Certification: Reconstruction of a rich and diversified ecosystem for the Boursay plantation (41)
  • October 2021 – Biodiversity for all certification: Reconstruction of a rich and diversified ecosystem for the Mulhouse plantation (68)

The company obtained the FSC ® Sustainable Forest Management Certification obtained in March 2021 on the experimental plot of Boursay (41) and in June 2022 on the Mulhouse plantation (68) (license number: FSC-C165212) as well as the Ecosystem certification Restoration by Preferred By Nature™ in June 2022 on these same two lands (certificate number: PBN-ER-061611)

5. Ethics Approach

 
Our business relations ethics charter is inspired by the rules of good conduct issued by ADEME in November 2019.

  • Rule 1: Establish a report of GHG emissions, reductions and offsets and make it public.
  • Rule 2: Choose labeled offset projects.
  • Rule 3: Give priority to projects with a sustainable development approach
  • Rule 4: Define the right combination of projects supported on national soil and projects supported internationally.
  • Rule 5: Communicate responsibly.

We never said it was the one solution to the climate challenge, but we say it's one of the essential transitions we need, and to do it at the scale of 1 trillion trees will clearly be extraordinarily difficult to achieve

Carbon offsetting is not greenwashing: it is fundamental to achieving carbon neutrality

Gerald Maradan – co-founder of EcoAct

Voluntary carbon offsetting is a financing mechanism by which a company, after having reduced its greenhouse gases (GHGs), offsets a quantity of non-reducible GHGs by sequestering an equivalent quantity elsewhere.
