03.3.3 Green corridor

A corridor is a linear structure of a network-like ecosystem type.

As a component of the network, a corridor can contribute to

connectivity but can also increase the total network area if it provides habitat [27]. In urban areas, built corridors come in a

variety of forms, such as streets providing critical infrastructure for cities such as transportation and energy, road tenure, and rail corridors. Surrounding the metropolitan landscape, these existing linear urban infrastructure new ones create excellent opportunities for dual functions as living corridors connecting fragmented living spaces in and around urban areas. elements impacting bee development and reproduction. The resilience of bees is dependent on habitat connectivity. In a

city, there may be numerous corridors, including highways

Figure 22: Corridor formation process and rail lines. At first sight, these passageways appear to have

numerous drawbacks. Bees‘ freedom of movement is constrai-

ned. Pollinators‘ movement is constrained after infrastructure

is created, and they lose their ability to identify powerful floral

odors [28]. Scents play a vital part in pollinator foraging acti-

vities. Pollinators such as bees detect aromas and attempt to

discover the source of the odors. This can be accomplished by

using visual images to track the gradient of the scent emanating from the source [28]. In the case of bees, after determining the source, the foraging bee returns to the hive and tells their colleagues of the source‘s position. It will be easier to visually identify the bloom source if it covers a broad region. However, when

the source, which is common in urban and suburban flowers, is

small and isolated, fragrances become more essential. pollen, are related to the strength of floral scents [28]. Furt-

hermore, other bee species, such as stingless bees, do not

employ „dance“ to communicate the position of the flower at

all; instead, they leave a fragrance trail between the nest and

the flower region to guide their nestmates to their food supply

[29]. An olfactory or fragrance corridor is necessary for pollina-

tors such as bees to find food, which aids in cross-pollinating

plants [29]. Pollinators, as well as plants, gain from the process due to the amount and diversity of pollinators. The existence of

linear constructions like highways, on the other hand, increases the distance between burrows and food sources, resulting in

a man-made barrier. Increasing the distance between a flower

source and the highway not only dilutes the fragrances, but it also makes it hard for some bee species to create a persistent

scent trail. Additional sources of stress include air turbulence

from automobiles, air pollutants from vehicle emissions, and

asphalt pavements.

However, when looking at the integrity of the habitat, corridors

contribute to bees‘ finding food and nesting along a road. Bees

fly at a certain distance, and green corridors create a functio-

ning habitat when this distance is paid attention to and a suitable environment is offered to them.
