Environment Bill

My Lords, in his argument against Amendment 196, which calls for biodiversity gain sites to be protected in perpetuity, the Minister suggested that they might receive protection under provisions that already exist. Could he specify what provisions might apply 30 years after establishment? For example, Medmerry, the project I referred to earlier, might become a Ramsar site even in that short timeframe. It is clearly designed to exist in perpetuity anyway, depending on the rise of sea levels. But would most sites really be likely to be eligible to become a SSSI, after 30 years?
