note on  gardens!!!

Good Morning All,  

Please see statement number 5 in the  summary.  Our pollinator gardens make 
a difference on the  landscape. 

Effects of land use at  a landscape scale on bumblebee 
nest  density and survival

Summary 
1.  We have little idea how landscape-scale  factors influence the success 
of wild bumblebee nests 
over time. Here for the first time we use molecular  markers to estimate 
within-season changes in the 
numbers of nests. 
2. Workers of two bumblebee species  were sampled in an arable landscape in 
late May–June and 
late July–August, and the numbers of nests represented in  each sample were 
estimated. We compare 
the methods available to estimate nest number from such samples and  
conclude that methods which 
allow for  heterogeneity in the probability of capture of nests provide the 
best fit to  our data. 
Changes in numbers of nests at  the two time points were used to infer nest 
survival. 
3. The two bee  species appeared to differ markedly in survival over time, 
with estimates of  45%of 
nests surviving for Bombus lapidarius and  91% for B. pascuorum. However, 
our data suggest that 
the foraging range of B. pascuorum may be greater in late  season, which 
would lead us to overestimate 
nest survival in this species. Differential survival may also reflect  
differences in phenology 
between the two  species. 
4. The land use class which had the most consistent effects on nest number  
and survival was gardens; 
for  B. lapidarius, the area of gardens within a 750 and 1000 mradius 
positively  influenced nest 
survival, while for  B. pascuorum, the number of nests in late samples was 
higher at sites with  more 
gardens within a 500 and 750-m  radius. For B. pascuorum, the area of 
grassland within a 250 and 
500-mradius also positively influenced nest number in  late samples, 
probably because this is the preferred 
nesting habitat for this species. 
5. The  importance of gardens is in accordance with previous studies which 
suggest  that they now 
provide a  stronghold for bumblebees in an otherwise impoverished 
agricultural  environment; furthermore, 
our  data suggest that the positive influence of gardens on bumblebee 
populations  can spill 
over at least 1 km into  surrounding farmland. 
6.  Synthesis and applications. The substantial effects that even small 
areas of local  resources such 
as rough grassland or  clover leys can have on bumblebee nest numbers and 
survival is of clear  
relevance for the design of pollinator  management strategies. 
Key-words:  Bombus, density, gardens,

FYI, see notes about importance of gardens to these  bees.
