“Houghton Regis Marl Lakes”的意思、由来-开放百科全书

The site is a large disused chalk quarry, and it is listed by Geo-East as a "Chalk Place to Visit" due to its exposure of Totternhoe stone.^[3]^[4] It is a rare example of standing water in chalk. It is important both ornithologically and for its range of dragonflies. There are two marl lakes, one deep and one shallow, which have aquatic plants and molluscs, with fens in a waterlogged area between the lakes.^[1]

The Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire managed the site between 2011 and 2015,^[5] . A Trust noticeboard at the northern and southern entrances to the site names it as Houghton Regis Chalk Pit. The Wildlife Trust BCN produced newsletters during their management period and these are [https://drive.google.com/drive/folders/1oqfkjpyic5VUibICG5jJ-Uco7Jxcec5h retrievable online]. Volunteers helped with tasks at various times^[6]. Youth Ranger activities^[7], took place and these included tasks such as scrub-clearing using conservation tools and controlled bonfires. The Chalk Pit regularly appeared in Wildlife BCN's North Chilterns Chalk volunteer programme^[8]

A Houghton Regis Chalk Pit Angling Club was running in 2015, set up to help combat irresponsible anglers who had damaged the environment and harmed wildlife by discarding their fishing tackle, littering, and campfires.^[9]. In 2016 there was an attempt to crowd-source funding for a fishing tackle shop^[10]

In April 2017 litter was reported to be a problem^[11]. In 2018 it was reported that a seat overlooking the chalk pit had disappeared.^[12] Following a hot July 2018, the Marl Lake was reported and demonstrated in pictures to have shrunk back, and suffering from the human nature of discarded plastic bottles and tin cans^[13].

There is pedestrian access by a footpath running between Fieldstone and High Street North.
