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

The northwest of Scotland is a stronghold for two of the UK’s rarest bumblebee species, Bombus distinguendus and Bombus muscorum.

The predominant form of agricultural land management in this region is crofting, a system specific to Scotland in which small agricultural units (crofts) operate rotational crop- ping and grazing regimes. Crofting is considered to be beneficial to a wide range of flora and fauna. How- ever, currently there is a lack of quantitative evidence to support this view with regard to bumblebee populations. In this study we assessed the effect of land management on the abundance of foraging bum blebees and the availability of bumblebee forage plants across crofts in northwest Scotland. The results of our study show that current crofting practices do not support high densities of foraging bumblebees. Tra ditional crofting practice was to move livestock to uplands in the summer, but this has been largely aban doned. Summer sheep grazing of lowland pasture had a strong negative impact on bumblebee abundance and forage plant availability throughout the survey period. The use of specific ‘bird and bee’ conservation seed mixes appears to improve forage availability within the crofted landscape, although the number of bees observed remained low. Of the forage plants available, the three most frequently visited species were from the Fabaceae. We therefore conclude that the creation of agri-environment schemes which promote the use of Fabaceae-rich seed mixes and encourage the removal of sheep grazing on lowland areas throughout the summer are essential in order to conserve bumblebee populations within crofted areas.

1. It has recently become apparent that there is cryptic diversity in bumblebees, notably in the Bombus lucorum complex which appears to contain three distinct taxa (B. lucorum, B. magnus, and B. cryptarum). We know almost nothing about how these species differ in their ecology or distribution. 2. Here, we use RFLP markers to identify workers of the B. lucorum complex from the west of Scotland, and we map the distributions, forage use and habitat associations of the three taxa. 3. In western Scotland, B. cryptarum was found to be the most abundant of the three related taxa, but all three occurred in almost all sample sites. In combination with similar work from Ireland, we are able to conclude that: B. cryptarum is a poly- lectic species associated with uplands and cool climates; B. lucorum appears to be a lowland bee particularly associated with urban areas and islands close to the main- land in Scotland, and feeding largely on Erica cinerea and Apiaceae; B. magnus appears to be a heathland bee strongly associated with feeding on Calluna vulgaris. 4. Our study demonstrates that a combination of molecular and ecological approaches can reveal aspects of the ecology of cryptic species.
