The northern Colletes mining bee is a UK Biodiversity Action\  Plan\  (UKBAP)\  priority\  species\  listed\  as Rare.
Since\  2001,\  nesting\  aggregations\  of\  this\  species\  have been monitored annually on the RSPB Reef reserve on the\  Isle\  of\  Tiree\  in\  the\  Inner\  Hebrides.\  Eight\  nest ing aggregations\  were\  found\  on\  the\  reserve\  in\  2001-2002, one was lost to natural causes in 2004 whilst three new aggregations\  were\  discovered\  in\  2005-6\  bringing\  the total\  of\  active\  aggregations\  to\  ten\  in\  2007\  and\  2008.
Seven of the nesting aggregations were associated with man-made\  features. This\  highlights\  the\  ability\  of\  the species\ \  to\ \  nest\ \  at\ \  new\ \  locations\ \  as\ \  they\ \  become suitable\  and\  suggests\  a\  possible\  management\  tool\  for enticing bees to nest in areas currently lacking suitable nest-sites.\  Management\  in\  the\  form\  of\  winter\  cattle grazing\  has\  maintained\  a\  stable\  population\  on\  the reserve.\ \ \ 
Since\  2000,\  surveys\  for\  northern\  Colleteshave\  been\  undertaken\  by\  staff\  and\  researchers\  from RSPB\ \  and\ \  Hymettus\ \  Ltd\ \  (formerly\ \  the\ \  Aculeate Conservation\  Group)\  in\  areas\  with\  historical\  records and\ \  of\ \  other\ \  potentially\ \  suitable\ \  herb-rich\ \  coastal habitat. These have revealed the continued presence of the\ \  bee\ \  at\ \  two\ \  sites\ \  in\ \  N.\ \  Ireland:\ \  Ballymaclary/Portstewart\ \ \  Strand/Umbra\ \ \  and\ \ \  White\ \ \  Park\ \ \  Bay/Bushfoot Strand, one in England: Duddon Estuary, and six\  in\  Scotland:\  Berneray\  to\  Vatersay\  in\  the\  Outer Hebrides, Tiree/ Coll, Islay, Colonsay / Oronsay, Irvine in\ \  Ayrshire\ \  and\ \  Machrihanish\ \  in\ \  Kintyre.\ \ 
Optimal habitat management for the bee is being encouraged in all these areas
