Our rocky shores are a challenging habitat for plant and animals to thrive on. Twice each day the intertidal zone is covered in saltwater and then exposed to the air and sun for varying periods of time. The battle to adapt to life on the intertidal has created one of our richest areas for biodiversity, with hundreds of plant and animal species to be found on any given stretch of our rocky shore.
The Explore Your Shore! Rocky Shore Safari is a survey designed to record the distribution of seaweeds and intetidal invertebrates around the Irish coastline. We are asking you to spend an hour of your time searching a rocky shore for our Big 30 tick list of Rocky Shore Safari species, but invite you to record any and all species you can find and identify.

When to Survey
Your survey should be conducted to coincide with low tide. For information on tide times check your tide tables or see:
Aim to start your survey 1-2 hours before low tide – survey of your lower zone box should coincide with low water.
What You Need:
- The paper form or the online webform with data access.
- A printed or digital copy of the Rocky Shore Safari Big 30! tick list.
- A camera or smartphone to take ID pictures.
- A fully charged mobile phone in case you need to call for assistance.
- Some guidebooks or online guides to the seashore… see exploreyourshore.ie for suggestions.
- Your Seashore Snapshots printable quadrats if you want to survey barnacles/limpets/mussels.
- At least 1 hour to dedicate to the survey once on the shore.
- Please complete a new survey form for each new shore visited and each new survey at that shore.
- Please record your details and the site details
- Please record your species on the paper/online form.
- The aim of the survey is to record as many intertidal species as possible, while endeavouring to find the species listed on the Rocky Shore Safari Big 30! tick list.
- This is a timed survey. There is no upper limit to how long you spend on the survey, but we ask that you spend a minimum of 20 minutes at surveying the upper, middle and lower shore respectively (e. 60 minutes in total). Please record the amount of time you spent (in minutes) surveying each section of the shore and the start time and finish time of your survey.
- Focus your search on a strip no more than 10m wide and please survey all the way from the high-water mark to the water’s edge. Please try to survey a representative amount of each part of the upper, middle and lower zones of the shore.
To help locate the lower, middle and upper zone on the shore, look for the following key seaweed species:
- Upper Zone – The upper zone lies at the top of the shore, nearest dry land. Look for classic upper zone seaweeds such as channelled wrack and spiralled wrack.
Channelled Wrack Spiral Wrack
- Middle Zone – The middle zone lies half-way along the slope of the shore between high water and low water. Look for classic middle zone seaweeds such as egg wrack and bladder wrack.
Egg Wrack Bladder Wrack
- Lower Zone – The lower zone lies adjacent to the sea at low water. Look for classic lower zone seaweeds such as serrated wrack and dulse.
Serrated Wrack Dulse
- Don’t forget to look under seaweed, rocks and search in cracks, crevices and rockpools. Be sure to carefully replace seaweed and rocks as you found them!
- Please take and submit a photograph of each species recorded – only species records with photographs can be submitted on our survey website.
- Upload your survey data using our online form.
- Bring a friend… surveying with friends or in groups can add to the enjoyment!
- Tell someone where you are going and when you expect to return
- Bring a fully charged mobile phone with you
- Please avoid surveying where weather warnings are in place for your survey area.
- Check the weather and tides before you leave for the shore
- Start your survey and hour or two before low tide. Aim to survey the lower zone around low tide.
- Ensure that you keep an eye on the tide and do not become trapped by the incoming tide.
- Dress appropriately for the weather
- Wear appropriate shoes for the ground you will be covering
- Do not attempt to survey dangerous shores or shores which are difficult to access.
- Keep away from areas of deep water.
- Keep away from the base of cliffs, where falling debris may be a hazard.
- If you get into trouble and require assistance, dial 999 or 112 and ask for the Coastguard.
