Distribution maps
The maps presented here provide visual information on the distribution of species in Israel from the past and present, and the changes in occupancy and breeding density during the comparison period. For further reading
Relative Abundance 2010-2020
Breeding density values in the current decade as determined from experts' opinion and observations from databases.
| Data Missing | Sporadic | Limited Sites | Low Density | High Density |
|---|---|---|---|---|
| 8 | 12 | 12 | 21 | 19 |
Relative Abundance 1980-1990
Density values based primarily on the book The Birds of Israel (Shirihai 1996).
| Data Missing | Sporadic | Limited Sites | Low Density | High Density |
|---|---|---|---|---|
| 5 | 14 | 14 | 17 | 22 |
Occupancy 1990-2020
The map shows differences in the species breeding distribution between the 1980's breeding map and the current weighted breeding evaluation. Negative value - species previously bred in the grid and is not presently breeding; positive value - species has not previously bred in the grid and is currently breeding.
| Data Missing | No Change | Occupancy Increase | Occupancy Decrease |
|---|---|---|---|
| 6 | 35 | 1 | 9 |
Change in Relative Abundance 1990-2020
The map shows the changes in the relative abundance of a species in each of the distribution grids between the breeding map of the 1980s and the weighted current breeding evaluation. Negative values - decline in abundance; positive values - increase in abundance; zero - no change in abundance.
