In which month should I map maritime vegetation?

Question

I'm studying habitat use by Brent Goose in the UK, a species that feeds on maritime vegetation. It's main food types are *Zostera* sp., *Ruppia* sp., *Ulva* / *Enteromorpha* sp. and *Puccinellia* sp. I plan to map these vegetation types on an inter-tidal mudflat in North-east England during the summer. I want to choose a month to map these vegetation types that will allow the most accurate mapping of their distribution of vegetation across the mudflat. I think there are two considerations 1. the month they easiest to identify 2. the month they are most visible. Which month should I choose?
