The Big Wildlife Garden website will enable people to join an accreditation scheme through which they can register their garden and obtain points for wildlife features, eventually achieving a certificate.
The core of the website is Google map software that will mean users can search for information on wildlife gardens throughout the UK.
The portal will include: a section called My Garden, where users can upload information about their own garden; a journal feature, where weekly activities and wildlife sitings can be recorded; and weekly tips. Information on the benefits of using certain features, such as a bird baths, is also included.
Natural England campaigns manager Jim Burt said: "It's about reaching out and connecting to people. By all contributing, we will be creating one big wildlife garden.
"The potential to record systematic information through the website's journal section is huge.We will have statistics on how many amphibians and birds are seen every day in UK gardens," Burt added.
