That concern of ours is illustrated in recommendation 1.43, where we recommended that they have “a long-term monitoring plan to assess the health and survival of the trees planted through the program” and “targets for the program's performance indicators” relating to that.
These benefits—carbon sequestration, biodiversity and human health—will accrue only if a good number of the trees survive. That was a significant weakness we identified. We've modelled based on the tree planting being successful, but it's not a given that it will be successful, especially with the increased incidence of forest fires.
