(NB: Most "records" will have multiple Species Information spreadsheets associated with them linked to the Site Information by the unique site code. These may include both declining and non-declining species.) 1M Unique Site Code (3-figure, as above) 2M Family: 3M Genus: 4M Species: 5 Microhabitat Cover (shaded/not shaded) (1=shaded, 0=not shaded) 6 Characteristic NON-breeding Habitat (1 & 2): 1. In stream/permanent/lowgradient 2. In stream/permanent/high gradient 3. In stream/temporary/low gradient 4. In stream/temporary/high gradient 5. In pond/permanent 6. In pond/temporary 7. On bank/stream/permanent/lowgradient 8. Onbank/stream/permanent/high gradient 9. On bank/stream/temporary/low gradient 10. On bank/stream/temporary/high gradient 11. On bank/pond/permanent 12. On bank/pond/temporary 13. On vegetation above stream/permanent/low gradient 14. On vegetation above stream/permanent/high gradient 15. On vegetation above stream/temporary/low gradient 16. On vegetation above stream/temporary/high gradient 17. On vegetation above pond/permanent 18. On vegetation above pond/temporary 19. On ground/dry 20. On ground/grass/scrub 21. On ground/temporarily flooded 22. Permanent marsh 23. In leaf litter 24. Subterranean (includes under rocks & logs) 25. Above ground in forest understory/general or unknown 26. Above ground in forest understory/trunks or branches 27. Above ground in forest understory/leaves 28. Above ground in forest understory/phytotelmata 29. In forest canopy/general or unknown 30. In forest canopy/trunks or branches 31. In forest canopy/leaves 32. In forest canopy/phytotelmata 7 Characteristic BREEDING Habitat: (1 & 2) (as above, where "stream"=running water & "pond"=still water) 8 Activity Period: (1=diurnal, 2=crepuscular, 3=nocturnal) 9 % Decline of Species (0,25,50,75 or 100% -default 25% when extent uncertain) 10 First Date Absent or Definite Decrease: (e.g. 198407) 11 Date of Last Available Information: (e.g. 198711) 12 Is Species Apparently Now Recovering? (1=yes, 0=no) 13 Life Stage Affected: (1=eggs, 2=larvae, 3=metamorphs 4=adults, 5=more than 1 stage affected) 14 Data Verification Source: (eg. Bloggs et al. 92/1 where 1= refereed paper 2=unrefereed paper/article or report 3=annecdotal information) 15 Species Comments (other information)
