Misconception of rapid ecological recovery after species loss
Problem
Many commenters note that the public and decision-makers commonly assume ecosystems will quickly rebound after species loss, but recovery may take millions of years or be permanently altered by invasive species, leading to conservation decisions based on mistaken expectations.
Pain points
- Assuming ecosystems will quickly return to equilibrium, ignoring long-term structural changes.
- The North Atlantic cod fishery did not recover after regulation; other species took over, leaving populations at lower levels.
- Even 100 years after logging, forest species richness and abundance remain lower than in unlogged forests, indicating slow recovery.
Questions to verify
- Do you believe ecosystems can recover quickly after species loss? What time scale do you consider reasonable?
- Have you encountered issues in real projects or policies due to underestimating ecological recovery time?
- Would a tool that provides long-term ecological recovery modeling help you with planning or decision-making?

On this topic, I can never end recommending Adam Curtis's series "All Watched Over by Machines of Loving Grace", and on this topic of "bounce back" the second episode in that series. The concept of "natural equilibrium" is a 1950s cybernetic machine fantasy projected onto the natural world rather than an accurate reflection of ecological reality.

I think what happened to the cod fishery off North America is really interesting. They overfished the cod then decided to regulate the fishery to let the population come back. But it never recovered - the cod population is stable but at a much lower number.

I had always assumed this, and my idea of nature bouncing back was more on the millions of years time scale as evolution would result in the refilling of empty ecological niches.
fact
Here's a study from the southern Appalachian Mountains that found that even in forests that were logged over 100 years ago, species richness and abundance was still lower than in forests that had never been logged: https://researchgate.net/publication/248428489_Centuries/...
