Although what you describe is accurate to some extent the current plan is what is available to us. The intent is to create a biological corridor that will link protected areas either directly or in close proximity. With Bacalar Chico to the North and the planned reserves to the west and the Hol Chan to the south I think this has been achieved.
You are also correct that there is a long way to go but a first step must be taken before any positive conclusion can actually occur. The folks who have been working on this are dedicated to making it work and they are also very aware of the challenges that will be faced going forward.
It should also be noted that Hol Chan is currently run locally and has been doing well overall. The same management may be able to expand a little and cover the additional area which is relatively small.
In the end the only way this project and others like will be successful is to include the area residents and hope that they understand the need for these types of reserves and volunteer or donate to make them successful.
