Analyze native and non-native plants to provide recommendations on which plants create an optimized environment for pollinator bees

Which plants are better for bees: native or non-native?

📖 Background

You work for the local government environment agency and have taken on a project about creating pollinator bee-friendly spaces. You can use both native and non-native plants to create these spaces and therefore need to ensure that you use the correct plants to optimize the environment for these bees.

The team has collected data on native and non-native plants and their effects on pollinator bees. Your task will be to analyze this data and provide recommendations on which plants create an optimized environment for pollinator bees.

💾 The Data

You have assembled information on the plants and bees research in a file called plants_and_bees.csv. Each row represents a sample that was taken from a patch of land where the plant species were being studied.

Column	Description
`sample_id`	The ID number of the sample taken.
`species_num`	The number of different bee species in the sample.
`date`	Date the sample was taken.
`season`	Season during sample collection ("early.season" or "late.season").
`site`	Name of collection site.
`native_or_non`	Whether the sample was from a native or non-native plant.
`sampling`	The sampling method.
`plant_species`	The name of the plant species the sample was taken from. None indicates the sample was taken from the air.
`time`	The time the sample was taken.
`bee_species`	The bee species in the sample.
`sex`	The gender of the bee species.
`specialized_on`	The plant genus the bee species preferred.
`parasitic`	Whether or not the bee is parasitic (0:no, 1:yes).
`nesting`	The bees nesting method.
`status`	The status of the bee species.
`nonnative_bee`	Whether the bee species is native or not (0:no, 1:yes).

💪 Challenge

Provide your agency with a report that covers the following:

Which plants are preferred by native vs non-native bee species?
A visualization of the distribution of bee and plant species across one of the samples.
Select the top three plant species you would recommend to the agency to support native bees.

🧑‍⚖️ Judging criteria

This is a community-based competition. The top 5 most upvoted entries will win.

The winners will receive DataCamp merchandise.

✅ Checklist before publishing

Rename your workspace to make it descriptive of your work. N.B. you should leave the notebook name as notebook.ipynb.
Remove redundant cells like the judging criteria, so the workbook is focused on your work.
Check that all the cells run without error.

⌛️ Time is ticking. Good luck!

# Convert date column to datetime format
data['date'] = pd.to_datetime(data['date'])

# Extract day, month, and year from date column
data['day'] = data['date'].dt.day
data['month'] = data['date'].dt.month
data['year'] = data['date'].dt.year

# Drop original date column
data.drop('date', axis=1, inplace=True)

# Preview updated dataframe
data.head()

# Count null values in the 'specialized_on' column
spl_null_count = data.isnull().sum()

# Calculate percentage of null values in the 'specialized_on' column
spl_null_pct = spl_null_count / len(data) * 100

# Display results
spl_null_pct

I droped 'specialized_on' and 'status' columns because their the almost miss 98% of their data

# Drop 'specialized_on' and 'status' columns
data.drop(['specialized_on', 'status'], axis=1, inplace=True)

# Preview updated dataframe
data.head()
